Correct option is A
Given:
New speed is of normal speed.
Delay time = 38 minutes.
Formula Used:
Time =
Solution:
Ratio of new speed to normal speed = 2 : 3
Ratio of new time to normal time = 3 : 2
Difference in time ratio = 3 - 2 = 1
1 unit corresponds to 38 minutes.
Normal time corresponds to 2 units.
Normal time = 2 × 38 = 76
Final Answer
So the correct answer is (a)
