Question 1011649
A car travelling at 48 kph overtakes a cyclist who is riding at 12 kph, has had a 3 hours head start. How far from the starting point does the car overtake the cyclist? 
----------------
The cyclist is 36 km ahead (3*12).
The car "gains on" the cycle at 36 km/hr (48 - 12).
36/36 = 1 hour to overtake.
48*1 = 48 km from the start.
