Question
Raman traveled a certain distance at a particular speed.
If he had traveled 6 km/h faster, he would have taken 30 minutes less. If he had traveled 5 km/h slower, he would have taken 30 minutes more. What is the distance in kilometers?Solution
Speed = 2S1S2/(S1 – S2) = (2 * 6 * 5)/(6 – 5) = 60kmph = (x/60-x/66) =1/2 = (11x-10x)/660=1/2 X=330km
