Question
Find the distance travelled (in km) by the truck to
reach point B from point A, if a car cover 45% the same distance in 2 hours 42 minutes and a truck covers 60% of the distance in 6 hours. The sum of speed of the car and truck is 160 km/hr.Solution
Let speed of car be s kmph Time taken by car travel total distance = 100/45 x 2.7 = 6 hrs Time taken by truck to cover total distance = 100/60 x 6 = 10 hrs so, s x 6 = (160 - s) x 10 6s = 1600 - 10s so, required distance = 100 x 6 = 600 km
