Question

In six hours A walks 10 kilometres more than B does in five hours; and in8 hours B walks seven kilometres more than A does in 5 hours. what are the speeds of each person?​

Answer 1

Answer:

Call their rates A and B. The equations become (since rate times time = distance):

6A - 5B = 10

8B - 5A = 7 (or -5A + 8B = 7)

Now solve this system of equations...multiply appropriately to get

30A - 25B = 50

-30A + 48B = 42

When we add these we get

23B = 92 and

B = 4 km/hr

A can be found by substituting into the first equation

6A - 5(4) = 10

6A = 30

A = 5 km/hr
