Q:

A) 32.1 km | B) 15.23 km |

C) 3.75 km | D) 32.1 m |

Answer: C) 3.75 km

Explanation:

Explanation:

Let 'd' be the distance between A and B

K -time = d/10 + d/9 = 19d/90 hours

L -time = 2d/12 = d/6 hours

We know that, 10 min = 1/6 hours

Thus, time difference between K and L is given as 10 minutes.

=> 19d/90 - d/6 = 1/6

=> (19d-15d)/90 = 1/6

=> 4d/90 = 1/6

Thus,

d= 15/4 km = 3.75 km.

hence the distance between A and B is 3.75 km.
