Boats and StreamsEasy

Two boats, travelling at 5 and 10 kms per hour, head directly towards each other. They begin at a distance of 20 kms from each other. How far apart are they (in kms) one minute before they collide?

Answer & solution

  • A

    112

  • B

    16

  • 14

  • D

    13

Solution

The distance between the boats one minute before they collide will be same as the total distance they travel in last one minute.

The boats together travel 10 + 5 = 15 km in 60 minutes.

∴ In one minute they can travel 14 km.

∴ They are 14 km part, one minute before they collide.

Hence, option (c).
