Jack and Tim were standing in the main street. The distance between the boys was x metres.
 At the same moment the boys started to move, Jack was running at a m/s and Tim walked at b m/s.

Find the time when the boys met if:
:
time = dist/speed
dist = x
:
a) they moved towards each other,
time = {{{x/((a+b))}}}
:
b) they moved in the same direction, walker in front.
time = {{{x/((a-b))}}}
