A man walks at 4 km/h. After 6 hours, he is overtaken by a cyclist who started 2 hours after him. What is the speed of the cyclist?
Show answer & explanation
Correct answer: C
Explanation
Distance covered by the man in 6 hours = 4 × 6 = 24 km
The cyclist started 2 hours after the man, so the time he took = 6 - 2 = 4 hours
Now, the speed of the cyclist = 24 ÷ 4 = 6 km/h
