Answer»

Let the distance will be covered by TEMPO be a km.

Given,

An auto rickshaw travels a distance of 36km.

RATIO of distance covered by auto rickshaw and tempo = 36 : a

Given,

Ratio of TIME taken by auto rickshaw and tempo = 2 : 3

Ratio of SPEEDS of auto rickshaw and tempo = 9 : 8

Use compounded ratio = Speed × Time

⇒ (9 : 8) and (2 : 3)

⇒ (9 × 2) : (8 × 3)

⇒ 3 : 4

Distance = speed × time

⇒ (36 : a) = (3 : 4)

⇒ 36/a = 3/4

⇒ a = 36 × 4/3 = 48

∴ The distance covered by Tempo in 3 hours is 48 km.
