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.

Step-by-step explanation:

Given

Speed of car is

We know, distance is given by

Let h represents the number of hours

So, the distance traveled with speed in 'h' hours

So, the expression is given by

irrational, then, just means all the numbers that aren't rational. every integer is a rational number, since each integer n can be written in the form n/1. however, numbers like 1/2, 45454737/2424242, and -3/7 are also rational, since they are fractions whose numerator and denominator are integers.
