If Ram covers a certain journey at 60% of his usual speed, he reaches the destination late by 36 min. His usual time (in min) to reach the destination is:
Answer & explanation
Correct answer: option 4
Let initial speed = 10
New speed = 60% of 10 = 6
As , Distance = Speed × Time
Speed and Time have indirect relationship .
Ratio Original : New
Speed 10 : 6
Time 6 : 10
According to question ,
4R = 36 min
1R = 9 min
Usual time = 6R = 6 × 9 = 54 min
