Question

two bycyclist do the se journey by travelling respectively at the rates of 9 and 10km an hour. find the length of the journy when one takes 32min longer than the other

Answer 1

48 Km.

Here we assume the distance between A and B is x km.

Therefore, x divided by 9-x divided 10 equals 32 divided 60 that is equal to 8 divided by 15.

Thus x divided by 90 is equal to 8 divided by 15 multiplied by 90.

Thus x is equal to 48km.
