Question

A man covered a distance of 280 km in 8 hours on a motorcycle. How much distance will be covered on a bicycle in 2 hours, if he rides the bicycle at `3/14` of the speed of the motorcycle?

विकल्प

• 25 km

• 15 km

• 20 km

• 24 km

Answer 1

15 km

Explanation:

Distance covered by man by motorcycle = 280 km

Time taken = 8 hours

∴ Speed of motorcycle = `280/8` = 35 km/h

So, speed of bicycle = `3/14 xx 35 = 15/2` km/h

Time = 2 hours

∴ Distance covered by bicycle = `15/2 xx 2` = 15 km.
