Answer:

62.5km/h

Explanation:

75 - 50 = 25

25 ÷ 2 = 12.5

50 + 12.5 = 62.5

or

75 - 12.5 = 62.5

For Example:

a motorist averaged 50km/h and 100km/h over two consecutive 50km stretches of road.

- Calculate the motorist's average speed of the whole journey?​

Answer:

75km/h

Explanation:

100 - 50 = 50

50 ÷ 2 = 25

50 + 25 = 75

or

100 - 25 = 75
