Manish travels from City A to City B. If Manish drives his car at of his normal speed, then he reaches City B 36 minutes late. Find the time (in minutes) that Manish would have taken to travel from City A to City B if he drove at his normal speed.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 18.
time = distance ÷ speed
At 1/3 speed, time = d ÷ (v ÷ 3) = 3d ÷ v = 3t
3t − t = 36
2t = 36
t = 18 minutes
