A car travels a distance of 15 km in 20 minutes. Find the speed of the car in :1) km h-1 2) m s-1

Answer 1

HERE IS YOUR ANSWER. ...


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/h.

Same way an hour has 3600 seconds so the speed for second is: (45km / 3600)/(1h / 3600) = 0.0125km/1s = 12.5m/s.

I hope I could help.
