The speed of a moving sidewalk at an airport is 6 ​ft/sec. A person can walk 42 ft forward on the moving sidewalk in the same time it takes to walk 10 ft on a nonmoving sidewalk in the opposite direction. At what rate would a person walk on a nonmoving​ sidewalk?


Please help I suck at story problems

42 / (r + 6) = 10 / r

42 r = 10r + 60
