Neil's dad wanted to measure the distance between the two tallest trees in their backyard and asked Neil to measure the distance with his footsteps. It was winter, so they were able to use the footprints left behind in the snow. They moved in the same direction starting from the second tallest to the tallest tree. Neil's footstep is 56 cm long and his dad's is 70 cm long. What is the distance between those two trees, in meters, if their footsteps overlapped 11 times?

7.7 m

Step-by-step 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
