Question
A car has to cover a distance of 240 km in 30 hours. If
it covers half of the journey in 3/5 th of the time, the speed to cover the remaining distance in the time left has to be:Solution
Total Distance = 240km Total Time = 30 hours He covers half of the Journey in 3/5th of the time = 30 × 3/5 = 18 hours Now remaining Distance = 240 – 120 = 120km Remaining time = 12 hours Speed to cover the distance of 120 km will be = 120/12 = 10km/hr
