Question

Ravi and John are standing 300 m apart. If they run towards each other with the speeds of 2 m/s and 1 m/s respectively, how much time will they take to cross each other?​

Answer 1

Answer:

100 seconds.

or 1 minute 40 seconds.

Step-by-step explanation:

Ravi travels at twice the speed of John.

So when they meet Ravi has travelled 200 m and John has travelled 100m.

So the time taken for them to meet is ( using Ravi's speed) = 100 * 1

= 100 seconds.
