Question

A car is traveling on a highway at a constant speed, described by the equation d = 70t, where d represents the distance, in miles, that the car travels at this speed in t hours. How many miles does the car travel in 1.2 hours?

Answer 1

84miles

Explanation:

Step one:

given data

we are told that the equation that describes the car's speed is

d = 70t-----------1

From the equation, we can see that the speed with which the car is traveling is 70miles per hour, while we are expected to find the distance d when the time is 1.2 hours.

Required

The distance d at 1.2 hours

Step two:

substituting in the expression we have

d= 70*1.2

d=84miles
