Rahul travels a certain distance
with a constant speed of 18 km/h and reaches 3 hours late. If he had travelled at a constant speed of 24 km/h, he would have reached on time. Find the distance Rahul travelled.Solution
ATQ,
Let the appropriate time taken by Rahul to travel the distance be 't' hours. Let the distance travelled by Rahul be 'd' km. Using the given information, we have: 18(t+3) = 18t+54 = d 24t = d Equating the distances: 18t+54 = 24t 6t = 54 t = 9 Calculating the distance = d = 24t = 24×9 = 216 km
