What is the average speed of the plane in miles per hour?

Question

it takes a plane 4 hours and 15 minutes to fly from Orlando, Florida to Boston, Massachusetts. The distance between the two cities is 1105 miles. what is the average speed of the plane in miles per hour.

 

Answer 1

v = d/t

 

d = 1105 miles

 

t = 4 hours and 15 minutes = (4 + 15/60) hours = (4 + 0.25) hours = 4.25 hours

 

v = 1105/4.25 miles/hour

 

Can you finish from here?

 

Answer 2

1105 / 4.25 = 260 mph

 

Please note that 4 hours and 15 minutes = 4.25 hours because 15 minutes is 1/4 hour or 0.25 hours

So 4 hours and 15 minutes is 4.25 hours.

 

Distance = rate x time

 

rate = distance / time

 

Based on the speed of the plane it does not appear to be a commercial airline which flies around 500 mph
