Question

In a race A beats B by 70m, B beats C by 80m. How much does A travel?

Answer 1

In a km race, A beats B by 70 m and B beats C by 80 m. How much did A beat B?

Distance between A and B is 70 m. You can write this as

A−B=70

Distance between B and C is 80 m. Write this as

B−C=80

Then distance between Aand C is

A−C=A−B+B−C

=70 m+80 m=150 m.

So, A beat C by 150 m.
