A car is traveling at

40 miles per hour.

Write a rational expression that gives the time that it takes the car to travel
Upper M miles.

time = M/40 hours

To find the time it takes for a car to travel Upper M miles, we can use the formula:

Time = Distance / Rate

In this case, the distance is Upper M miles and the rate is 40 miles per hour.

So the rational expression for the time it takes the car to travel Upper M miles would be:

Time = Upper M / 40

To write a rational expression that gives the time it takes for a car to travel Upper M miles, we can use the formula:

Time = Distance / Rate

In this case, the distance is Upper M miles, and the rate is 40 miles per hour.

So, the rational expression that represents the time it takes for the car to travel Upper M miles is:

Time = Upper M / 40

Therefore, the rational expression is:

Time = Upper M / 40
