Question

An airliner travels 25 miles in 300 seconds, what is the speed of the airliner in miles per hour.

Answer 1

Answer:

300 mph

Step-by-step explanation:

You have to do a conversion of 300 seconds.

$\text{300 seconds} \dfrac{1 minute}{60 sec}*\dfrac{1 hour}{60 minutes}$

$\dfrac{300}{3600} = \dfrac{1}{12}\text{hour}$

300 sec = 0.083333 hours.

Formula

d = r * t

Givens

t = 0.0833333 hours

d = 25 miles

r = ??

Solution

25 miles = r * 0.083333333 hours

r = 25/ 0.08333333

r = 300 miles / hour
