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?
