Answer: 7.7 m
Explanation:
Given that Neil's footstep is 56 cm long and his dad's is 70 cm long.
If their footsteps overlapped 11 times, this shows that the longer footstep will surely be 11 different steps since the difference between the two footsteps is not upto the half of the smaller one.
The distance between the two trees will be 70 cm × 11 = 770 cm
Convert centimeters to meter by dividing it by 100
770/100 = 7.7 meter.
Therefore, the distance between the two trees in metre is 7.7 m
