Seth and brian ran the 200 yard dash at the track meet. brian reached the finish line in 30 seconds. seth ran 25 feet per second. who finished the race first? explain your reasoning.

Ok so we know that brian took 30 seconds to finish the race, but we don't know how long seth took. The problem told us the race was 200 yards and that seth ran 25 feet per second. From those two pieces of information, we can figure out how many seconds it took seth to run 200 yards. Since the problem told us he ran 25 FEET per second, we will convert the length of the track from yards to feet. There are 3 feet in a yard, so the track is 600 feet. Since he ran 25 feet per second, if we divide the length of the track by the speed he ran, we will get how long it took him to run. So 600 divided by 25 will give us 24 seconds. So Brian ran the race in 30 seconds and Seth ran it in 24, so Seth ran the race the fastest!
