Car travel

The responses to these questions can be used to determine the number of elevators required, the size of the car, the door arrangement and the speed of car travel. Other major considerations should be the location of elevators within the building and accessibility for disabled users. 

The cost of these drives is significantly greater than that of a comparable geared drive, but the quality of ride and maximum speed of car travel are much improved. Gearless drives usually have applications in prestige offices and hotels where the elevator travel is in excess of 35 m. 

Assuming that a car travels at an average speed of 50 miles per hour, how many miles must be driven before a fatality is expected ... 

The effects of transport on economy, people and on the environment are manifold. They include the consequences of transport accidents and fatalities, nuisance and health effects caused by steady noise exposure, air emissions and the exhaust and resuspension of particles, climate impacts by the emission of greenhouse gases, soil and water contamination, and the deterioration of natural habitats. Moreover, the financial burden of infrastructure provision and the additional travel and production costs caused by congestion should be mentioned but these items are mainly borne by transport users themselves and thus are only partly imposed on society as a whole. Not all of these effects are equally relevant for all means of transport. While accidents constitute the major problem of car travel, the railways definitely face a noise problem and air transport contributes most to the emission of climate gases. 

How far will a car travel if it is running at a constant speed of 5 3 miles per hour for 4 and one-half hours ... 

A car s fuel tank holds 15 gallons of gasoline. How far can the car travel on a full tank of gas, if the fuel efficiency is 23 miles per gallon ... 

A toy car travels a distance of 7,620 cm in four minutes. What is the speed in inches per second ... 

The busiest place on Highway 99 is Nino and Gus s Hubcaps Galore. Nino and Gus polish hubcaps and replace lost hubcaps. There are a lot of cars traveling on Highway 99 and some of them lose hubcaps. Nino called to Gus, "Hey Gus, come over here for a minute "... 

During the 2008 Hydrogen Road Tour, hydrogen-powered cars traveled the roads of 18 states. 

The two solutions have the same initial concentration. When they are combined, the final concentration is also the same. (The two initial solutions and the final solution would all taste equally sweet. Try it.) As an analogy, if a car travels 50 mph during the first half of a trip and 50 mph during the second half of the trip, its overall speed is 50 mph. Alternatively, we may calculate the final concentration ... 

Research your favorite type of car. How does this car run How far can this car travel before refueling What pollutants does this car produce ... 

A rate indicates how fast something changes with time. In a savings account, the rate of interest tells how your money is growing over time. Speed is also a rate. From the speed of one of the race cars shown in Figure 1, you can tell the distance that the car travels in a certain time. If a car s speed is 67 m/s (150 mi/h), you know that it travels a distance of 67 meters every second. Rates are always measured in a unit of something per time interval. The rate at which the car s wheels turn would be measured in revolutions per second. The rate at which the car burns gasoline could be measured in liters per minute. 

We are all familiar with processes in which some quantity changes with time— a car travels at 40 miles/hour, a faucet delivers water at 3 gallons/minute, or a factory produces 32,000 tires/day. Each of these ratios is called a rate. The rate of a reaction describes how fast reactants are used up and products are formed. Chemical kinetics is the study of rates of chemical reactions, the factors that affect reaction rates, and the mechanisms (the series of steps) by which reactions occur. 

An analogy for the rate-determining step is the flow of traffic along a narrow road. Assuming the cars cannot pass one another on the road, the rate at which the cars travel is governed by the slowest-moving car.
