Answer 2

Answer: The required time taken to drive 135 miles is 3 hours.

Step-by-step explanation: We are given to find the time taken to drive 135 miles at a speed of 45 miles per hour.

We will be using the UNITARY method to solve the problem.

We have

Time taken to drive 45 miles = 1 hour.

So, time taken to drive 1 mile will be

`(1)/(45)~\textup{hour}.`

Therefore, the time taken to drive 135 miles is given by

`(1)/(45)*135=3~\textup{hours}.`

Therefore, the required time taken to drive 135 miles is 3 hours.
