| B starts 4 minutes after A from the same point, for a place at a distance of 7 miles from the starting point. A on reaching the destination turns back and walks a mile where he meets B. If A’s speed is a mile in 8 minutes then B’s speed is a mile in ____ minutes.

A. 9

B. 12

C. 10

D. 8

### Right Answer is: C

#### SOLUTION

A.T.Q.

Since A covers 1 mile in 8 minute.

Distance covered by A in 4 min = 1/8 × 4 = 0.5 mile

Total distance covered by A to meet B

mile

Time taken by A to cover 7.5 mile

= 7.5 × 8

= 60 min

B covers 6 mile to meet A in 60 minutes

Therefore, B covers 1 mile in 10 minutes.
