Question

A car travels at a constant speed of 40 mph on the highway. Write an expression to find the distance the car travels for any number of hours. Let the variable h represent the number of hours.

Answer 1

Answer: $40h$

Step-by-step explanation:

Given

Speed of car is $40\ mph$

We know, distance is given by

$\text{Distance=}\text{speed}\times \text{time}$

Let h represents the number of hours

So, the distance traveled with speed $40\ mph$ in 'h' hours

$\Rightarrow d=40\times h\\\Rightarrow d=40h$

So, the expression is given by $40h$
