Question

The distance travelled by a car is 15km. If the car travelled at an average speed of 50km/h, how long did the trip take? Show working out.

Answer 1

18 minutes

Explanation:

Given distance (D) and average speed (S) then time (T) is calculated as

T =
`(D)/(S)` =
`(15)/(50)` =
`(3)/(10)` hour

`(3)/(10)` hour =
`(3)/(10)` × 60 min = 3 × 6 = 18 mins
