Q)

# A bus covers a distance of 66 kms in 90 minutes where as a truck covers a distance of 1100 metres in 2 minutes. The ratio of their speeds is :

( A ) 4:3
( B ) 5:3
( C ) 3:5
( D ) 45:33

Bus speed = $\frac{66*60}{90} = 44$ km/hr
Truck speed = $\frac{1.1*60}{2} = 33$ km/hr
So ratio of bus to truck speed = $\frac{44}{33} = \frac{4}{3}$
