Simultaneously 80154

A pedestrian and a cyclist set off simultaneously from two villages 24 km apart. The pedestrian walked at an average speed of 4 km/h and met the cyclist after ninety minutes of walking. What was the average speed of the cyclist?

Correct answer:

v2 =  12 km/h

Step-by-step explanation:

s=24 km v1=4 km/h t=90 min h=90:60  h=1.5 h  s1+s2=s  v1 t+v2 t=s 4 1.5+v2 1.5=24  1.5v2=18  v2=1.518=12  v2=12=12 km/h
