Question
The average speed of a bus is half the speed of a train.
The train covers 5200 km in 13 hours. How much distance will the bus cover in 36 minutes?Solution
. Distance covered by train = 5200 km, Time= 13 hrs. Speed of a train = `5200/13` = 400 km/hr. Average speed of a bus = `1/2` × 400 = 200 km/hr. Time= 36 minutes = `36/60` = `3/5` hrs. Distance covered by bus = Speed × Time = 200 × `3/5` = 120 km.
