if stone fall 64.4 ft in 2 sec x ft would be in three seconds
64.4ft : 2 = x : 3
from this we got
The speed (r) of a race car around a track varies inversely as the time it takes to go one lap around the track. When Car 44 is traveling 170 mph, it takes him 1.5 mins to complete one lap around the track. If he can complete a lap in 1.45 mins, how fast would he be traveling?
The distance a stone falls when dropped off a cliff is proportional to the square of the time it falls. If the stone falls 64.4 ft in 2 secs, how far would it have fallen in 3 secs?
No entiendo. I don't understand. Thanks for any help!
