The distance between two cities is 128km. The time taken to travel between the two cities is

Question:

The distance between two cities is 128km. The time taken to travel between the two cities is the distance divided by the average speed (skm/h).

a. Write a formula for the time (T) taken to travel between the two cities.

b. Calculate the time taken to travel between the two cities if the average speed was 80km/h.

The time taken is 1.6 hours.

c. Calculate the average speed if the time taken to travel between the two cities was 2.5 hours.

Rearranging the formula to make the average speed s the subject gives:

The average speed is 51.2km/h.
