A bouncing tennis ball rebounds each time to half the height of the previous bounce. It is dropped from a height of 16 m. The total distance traveled when it hits the ground for the 10th time is $A\dfrac BC$ metres. Find $A-B-C$.
Interpret the displayed expression as a mixed number in lowest terms: $A$ is the whole-number part and $0<B<C$, with $B,C$ coprime positive integers.
