Ken can beat Jim by 100 meters in a 1,000-meter race, and Jim can beat Bob by 10 meters in a 100-meter race. If both run at the given rate, by how many meters will Ken beat Bob in a 1,000-meter race?

Jim can beat BOB by 10 m in 100 m means that in 1000m it is 100m difference. So Ken runs 100m faster than Jim who beats another 100m of Bob. So Ken will beat Bob by 100+100=200m
