Question
A bicycle moves at 30 km/h and needs 9 hours to complete
a journey. A van completes the same journey in 3 hours. If the bicycle's speed is increased by 20% and the van's speed is reduced by 30%, find the new speed difference between the bicycle and van.Solution
ATQ, Distance = 30 × 9 = 270 km Speed of the van = 270 / 3 = 90 km/h Increased speed of the bicycle = 30 × 1.2 = 36 km/h Decreased speed of the van = 90 × 0.7 = 63 km/h Required difference = 63 - 36 = 27 km/hr (van is faster)
