Question
The speed of an electric car is 100 km/h, taking 7 hours
to traverse a distance. A bus takes 5 hours to cover the same distance. If the electric car's speed is increased by 25% and the bus's speed is decreased by 15%, find the difference between their new speeds.Solution
ATQ, Distance = 100 × 7 = 700 km Speed of the bus = 700 / 5 = 140 km/h Increased speed of the electric car = 100 × 1.25 = 125 km/h Decreased speed of the bus = 140 × 0.85 = 119 km/h Required difference = 125 - 119 = 6 km/hr
