Question
Neha and Riya start together from point P to point Q.
The ratio of their speeds is 4:3. If Riya takes 30 minutes more than Neha to reach point Q, find the time Neha takes to reach point Q.Solution
ATQ,
Ratio of speeds of Neha : Riya = 4 : 3
Therefore, ratio of time taken = 3 : 4
Time difference = 4 - 3 = 1 part
1 part = 30 minutes = 0.5 hours
So, Neha's time = 3 parts = 3 × 0.5 = 1.5 hours
