Question

In a 1000m race A beats B by 100m and B beats C by 100m then find by how much meters did A beats C.

Answer 1

A beat C by 200 m since B is 100m behind A and C is 100m behind B

Answer 2

As the distance between A and B is 100 m
and distance between B and C is 100 m
⇒A---------B-------------C
       100 m   100 m
Distance between A and C = AB+BC
                                            =100+100
                                            =200 m
