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`

Explanation:

Given

Speed of car is
`40\ mph`

We know, distance is given by

`\text{Distance=}\text{speed}* \text{time}`

Let h represents the number of hours

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

`\Rightarrow d=40* h\\\Rightarrow d=40h`

So, the expression is given by
`40h`
