A runs 25% faster than B and is able to give him a start of 7 metres to end a race in dead heat. What is the length of race?

35 metres

Step-by-step explanation:

The question states that A runs 25% faster than B. This means that, for every 1 second that B runs, A runs 1.25 second

Assuming that the total length of the race, that we're looking for, is D. Then we can say that B made a total distance of D-7 meters, and A runs D.

time taken by A =

time taken by B =

equating both together, we have

=

1.25D  - 8.75 = D

1.25D - D = 8.75

0.25D = 8.75

D = 8.75/0.25

D = 35

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.
