Average speed

The average speed of a pedestrian who walked 10 km was 5km/h, the average speed of a cyclist on the same track was 20km/h. In how many minutes did the route take more than a cyclist? Q

Correct answer:

x =  90 min

Step-by-step explanation:

s=10 km v1=5 km/h v2=20 km/h  t=t1t2 t1=s/v1=10/5=2 h t2=s/v2=10/20=12=0.5 h  t=t1t2=20.5=32=1.5 h  x=t min=t 60  min=1.5 60  min=90 min
