Amodel airplane flew a distance of 330 feet in 15 seconds. select all unit rates that are equivalent to the speed of the model plane. 12 mph, 1056 ft per min, 1320 ft per min, and 15 mph. i put in 36 points

Option C and D are equivalent to the speed of the model plane

Step-by-step explanation:

Distance  = 330 feet

Time = 15 seconds

Speed of airplane =

Convert it into miles per hour

1 feet = 0.000189394 miles

3600 seconds = 1 hour

So, 1 second =

Speed of airplane in miles /hr =

Speed of airplane in miles /hr =

So, Speed of airplane in miles /hr is 15 miles per hour

Convert speed into feet per minute

60 seconds = 1 minute

Speed of airplane in feet / minutes =

Speed of airplane in feet / minutes = 1320 ft/min

So, Option C and D are equivalent to the speed of the model plane
