The velocity of a falling object in a vacuum is directly proportional to the amount of time the object has been falling. If after 5 seconds an object is falling at a speed of 90 miles per hour, how fast will it be falling after 18 seconds? | [
"216 miles per hour",
"90 miles per hour",
"5400 miles per hour",
"324 miles per hour"

Velocity =k*Timewhere k is the constant of proportionality
Time= 5 seconds
Velocity = 5k = 90 miles per Hour
i.e. k = 18
i.e. The relation between Velocity and Time becomes
Velocity =18*Time
Time= 18 seconds
Velocity = 18*18 = 324 miles per hour
