Answer:

44.8 mph

Step-by-step explanation:

Betsy drove from london to wolverhampton.it took her 2.5 hours at an average speed of 56 miles per hour.Mac drove the same journy by motor bike.It took him 2 hours.Assuming that both took the same route,work out Mac's average speed in mph.

The above question is solved using Proportion method

2.5 hours = 56 mph

2 hours = x mph

Cross Multiply

2.5 hours × x mph = 2 hours × 56 mph

x mph = 2 hours × 56 mph/2.5 hours

x mph = 44.8 mph

Therefore, Mac's average speed = 44.8 mph
