Answer 2

It will take 2.5 hours to drive home.

Step-by-step explanation:

Engineer Kweku takes time to drive to his brother's house = 3 hours

His average speed was 50 miles per hour.

Distance = speed × time

               = 50 × 3

               = 150 miles.

Distance between his house and his brother's house = 150 miles

If his average speed is 60 miles per hour.

To calculate time we use formula :

$Time=\frac{Distance}{speed}$

           $=\frac{150}{60}$

           = 2.5 hours

It will take 2.5 hours to drive home.
