Bhanu travels from City A to City B. If Bhanu drives his car at of his normal speed, then he reaches City B 51 minutes late. Find the time (in minutes) that Bhanu would have taken to travel from City A to City B if he drove at his normal speed.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 17.
Let normal time = t minutes
At 1/4 normal speed, time taken = 4t
He is 51 minutes late, so:
⇒ 4t - t = 51
⇒ 3t = 51
⇒ t = 17
