Amodel airplane flew a distance of 330 feet in 15 seconds.

Convert unit rates: a model airplane flew a distance of 330 feet in 15 seconds. Select ALL of the unit rates that are equivalent to the speed of the model airplane.

A. 12 miles per hour
B. 1056 feet per minute
C. 15 miles per hour
D. 1320 feet per second

The unit rate of the speed in feet per second is given by 330 feet / 15 seconds = 22 feet per seconds.


330 feet = 330 / 5280 miles = 0.0625 miles
15 seconds = 15 / (60 x 60) hours = 15 / 3,600 hours = 0.004167 hours
The unit rate of the speed in miles per hour is given by 0.0625 / 0.004167 seconds = 15 miles per hour.


15 seconds = 15 / 60 minutes = 0.25 minutes
The unit rate of the speed in feet per minute is given by 330 feet / 0.25 minutes = 1,320 feet per minute.

Therefore, the only unit rate that are equivalent to the speed of the model airplane is 15 miles per hour.

A. p = 2(l + w)p/2 - l = ww = p/2 - l b. while isolating the variable w in the equation, i first divided both sides by 2 and then i subtracted l from both sides. i hope this .

How am i goonna know explain
