Question

an airplane is traveling at a constant speed of 600 miles per hour. How many feet does it travel in 10 seconds? Remember that 1 mile is 5280 feet.

Answer 1

Hello!

The answer is:

The airplane will travel 8800 feet in 10 seconds.

Why?

It's a conversion exercise, we need to be careful in order to solve it with no mistakes.

First:

We need to remember that 1 hour is equal to 60 minutes, and 1 minute is equal to 60 seconds, so, to calculate how many seconds are in one hour, we need to perform the following operation:

`Time=1hour*(60minutes)/(1hour)*(60seconds)/(nminute)=3600seconds`

Second:

We need to convert from miles to feet, we need to remember that 1 mil is equal to 5280 feet.

So, solving we have:

`Speed=600(miles)/(hour)*(1hour)/(3600seconds)*(5280ft)/(1mile)=880(ft)/(seconds)`

Now, calculating how many feet does it travel in 10 seconds, we have:

`distance=speed*time\\\\distance=880(ft)/(seconds)*10seconds=8800ft`

We have that the airplane will travel 8800 feet in 10 seconds.

Have a nice day!
