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? .

Using the formula:
d = r x t
9 sec after the race started is 8 sec after
he started sprinting
d=9.8
d=72
So, he has gone  8 + 72= 80 m
That means he is  100 - 80 = 20 m from the finish line.
Putting into a formula:
Let,
d  = distance from the finish line after 9 sec
d=100-(9(9-1)) - 8
d= 20 m

The answer is : 63explanation 60 times 0.05360+363
