The ratio of steps is 3:4. Carly's steps are .5 m each, so multiplying this value by her 3 steps gives us 1.5 m in the expanded ratio value 1.5m to Jim's unknown value. Now divide 1.5 m by Jim's 4 steps to give us .375 m per each of his steps. Then multiply Jim's 24 steps by .375 m to give us the distance in meters his 24 steps travel: 9 meters.
