Question

James covers a distance of 8 meters in the first second of a 100 meter race. Then, he sprints at a speed of 9 meters per second. How far is James from the finish line 9 seconds after the race has started?

Answer 1

in the first second he covered 8m
then in the 8 more seconds he covered 8*9=72m

so he totally covered 72+8=80m
the distance left is 100-80=20m

thus he is 20m far from the finish line
