### Question

A cyclist travels at a speed of 8km/h. Had he travelled at 16km/h he would have covered a distance of 64 km more. What is the total distance travelled by him?

**A**

64 km.

**B**

65 km.

**C**

63 km.

**D**

66 km.

**Soln.**

**Ans: a**

By the given problem, the time is same for both cases. If the total distance covered by him at 8km/h is x, then, $x/8 = {x + 64}/16$. Solving, we obtain x = 64 km.
