The formula for constant speed is: distance = speed x time Solving for time, it turns out that you simply have to divide distance by speed.
D = 60T where T is expressed in hours.
A car travelling at a constant speed of 75km/h for 2 hours will travel a distance of 150km.

Not necessarily. The distance a car travels is determined by its speed and the time it spends traveling. If a car is traveling at a slower speed but for a longer period of time, it may not cover as much distance as a car traveling at a faster speed but for a shorter period of time. So, the longest time does not always correspond to the greatest distance traveled.
No. In general, for the simplified case of constant speed, use the formula: distance = speed x time
Not necessarily. The speed at which the car is traveling also plays a significant role in determining the distance covered. A car traveling at a slower speed can travel for a longer time and cover less distance than a car traveling at a higher speed for a shorter amount of time.
The formula for constant speed is: distance = speed x time Solving for time, it turns out that you simply have to divide distance by speed.
The distance traveled by an automobile moving at a constant velocity is equal to the product of the velocity and the time traveled. This relationship assumes no changes in velocity or direction during the motion.
The distance vs. time graph in figure 1a shows a car is at rest for the initial time period, then moves with a constant positive velocity for a while until it comes to a stop again. This indicates the car accelerates, maintains a constant velocity, and then decelerates to a stop.
The standard formula for constant speed problems: distance = speed x time In this case, you need to divide the distance by the speed.
The formula, distance = speed x time, or speed = distance / time, assumes constant speed. If the speed changes, then the formula speed = distance / time will give you the average speed over the time period. To get the instantaneous speed in this case, you must divide distance / time for a very short time interval.
