Question 12
Rabby the rabbit plants carrots along a bed 6 m long. Neighbouring plants are 20 cm apart: the holes are circular, their adjacent centres are 20 cm apart, and the hole size is negligible. After harvesting, he wants to reuse the carrot holes to plant cabbages, but neighbouring cabbages must be 50 cm apart. How many holes stay in use? There is a hole at each end of the bed.
