Find Time of Journey Bovered by A
Answer: (1) 15 minutes
Let be the speed of C = P
Then, the speed of B = 3P
The speed of A = 6P
Therefore, the ratio of speed of A and C = 1 : 6
Time taken by C to covered journey = 3/2 hours.
the speed of C is 6 times less than A.
Then, A will take 1/6 of the total time taken by C.
Therefore, time taken by C to covered same distance = 3/ 2 x 6
= 3/12 = 1/4 hr.
1 hr = 60 min
Therefore, 1/4 hr = 1 x 60/4 = 15 min.
Hence, the answer is (1) 15 min.
