Question

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

Answer 1

300 mph

Explanation:

You have to do a conversion of 300 seconds.

`\text{300 seconds} (1 minute)/(60 sec)*(1 hour)/(60 minutes)`

`(300)/(3600) = (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
