The speed of a bus from university a to university b was increased by 20% to 48 miles per hour. what was the speed of the bus from university a to university b before the increase?

The speed of the bus is 40mph.

Step-by-step explanation:

Given that increase in 20% causes the bus to drive at 48mph. In order to find the original speed, we can assume that the original speed is 100% :

100% + 20% = 48mph

120 % = 48mph

1% = 0.4mph

100% = 40mph
