A car travels 81miles at 40 mph how long would it take the car to travel that?

The car is traveling at 40 miles per hour (mph) and the distance it has traveled is 81 miles. You can use the distance equation, which is d = rt, where d stands for distance, r stands for rate of travel/speed, and t stands for time.

In this case, you will substitute in your known values and solve for the variable you don't know:

d = rt

81 = 40t

To find out how long it takes for the car to travel 81 miles at a rate of 40mph, you will need to solve for the variable (t), which stands for time.
