Jason Runs 100 yards in 15 seconds How Many feet can jason run in 15 seconds

SpyIntel [72]

Answer:

He can run 20 ft in 15 seconds

Step-by-step explanation:

we need to change yards to ft

3ft = 1yd

100 yds * 3ft/1yd = 300 ft

distance = rate * time

300 ft = rate * 15 seconds

divide by 15 seconds on both sides

300 ft/15 seconds = rate

20 ft/sec

He can run 20 ft in 15 seconds
