Question
Rakesh travels a certain distance with a constant speed
of 24 km/h such that he reaches 2 hours late. If he travelled at constant speed of 30 km/h he would have reached on time. Find the distance travelled by Rakesh.Solution
Let the appropriate time taken by Rakesh to travel the distance = 't' hoursLet the distance travelled by Rakesh = 'd' kmWe have, 24(t + 2) = 24t + 48 = dAlso, 30t = dSo, 24t + 48 = 30tSo, 6t = 48So, t = 8So, d = 30t = 30 X 8 = 240 km
