The average speed of a bus is one-third of the speed of a train. The train covers 1125 km in 15 hours. How much distance will the bus cover in 36 minutes?

A 12 km

B 18 km

C 15 km

D 75 km

Solution

Correct Answer: Option C

ট্রেনের গতি = ( 1125/15 ) = 75 km/hr

∴ বাসের গতি = {75×(1/3)} = 25 km/hr

বাসটি 60 মিনিটে দূরত্ব অতিক্রম করে = 25 km 

∴ বাসটি 36 মিনিটে দূরত্ব অতিক্রম করে = {25×(36/60)} = 15 km
