Question
Barry drives his car at a speed of 48 miles per hour. If he covers a total distance of x miles then which of the following function correctly models the time taken by him to cover x miles?
Solution
The time taken to cover a certain distance is given by the formula:
Time = Distance / Speed
In this case, Barry's speed is 48 miles per hour and the distance he covers is x miles. So, the function that models the time taken by him to cover x miles is:
Time = x / 48
So, the function is T(x) = x / 48, where T(x) is the time taken to cover x miles.
