Question

A man travels at a rate of 25m/sec. If he travels for 10½hrs, how many kilometres has he covered?

Options

A) 262.5

B) 945

C) 970

D) 995

E) 1822.9

The correct answer is B.

Explanation:

A distance of 1 second = 25m
A distance of 60 seconds (I minutes ) = 60 x 25 = 1500m
A distance of 630 minutes (Time in minutes) = 1500 x 630= 945 000

Distance in kilometers = 945 000/1000= 945km
