Answer is 45km/h

the car travels 15km in 20 minutes, and 20 minutes are a third of an hour, so the speed per hour is : (15*3 &2*30
= 45km/60min, as 60min is an hour so it’s equal to 45km/h.

Answer:
Explanation:
Time=20 min=20/60hr=0.33hr
20*60sec=1200sec
Distance=15km=15*5/18m=4.16m
so,speed in km/h:
distance/time=15/0.33=45.45km/hr
speed in m/s:
distance/time=4.16/1200=0.0034m/s
