Two bicycles are driving on the circle in the same direction with speeds of 9 mph and 5 mph respectively. How many points are there on the circle where the two bicycles meet.

Given that,

Speed of first bicycle = 9 mph

Speed of second bicycle = 5 mph

Suppose the length of the circle 24 miles.

We need to find the relative velocity

Using formula of relative velocity

Put the value into the formula

We need to calculate the time

Using formula of time

We need to calculate the distance of the points where the two bicycles meet

Using formula of distance

For first bicycles,

For second bicycles,

Hence, The points where the two bicycles meet after every 6hr at 30 miles and 54 miles.
