Question

A car takes 20 mins to cover a distance of 15 km. calculate its speed in km/h and m/s.

Answer 1

Answer:

45km/per hour

Step-by-step explanation:

If the car travels 15km in 20 minutes, and 20 minutes are a third of an hour, so the speed per hour is : (15km * 3)/(20min * 3) = 45km/60min, as 60min is an hour so it's equal to 45km/or hour

Answer 2

Answer:

speed = distance / time

speed = 15/20

speed = 3/4

speed = 0.75 km/h , 0.2083333 m/s
