Answer: The answer is 48 miles.
Step-by-step explanation: Given that the bus travels 36 miles in 45 minutes.
We are to find the distance in miles that the bus will travel in 60 minutes.
Obviously, we will be using unitary method to solve this problem. Here it goes.
In 45 minutes, distance travelled by bus = 36 miles
In 1 minute, the distance travelled by bus

∴ In 60 minutes, distance travelled by bus is given by

Thus, the required number of miles is 48.
