Question
A bus travels from point A to point B at a speed of 48 km/h
and makes the return trip from B to A at a speed of 56 km/h. If the total time taken for the round trip is 39 hours, what is the distance between points A and B?Solution
Let the distance between ‘A’ and ‘B’ be ‘x’ km
According to the question,
(x/48) + (x/56) = 39
Or, (7x + 6x)/336 = 39
Or, 13x = 336 × 39
Or, x = 1008
Therefore, distance between ‘A’ and ‘B’ = 1008 km
