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
frez [133]
<h2>Hello!</h2>

The answer is:

The airplane will travel 8800 feet in 10 seconds.

<h2>Why?</h2>

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*\frac{60minutes}{1hour}*\frac{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\frac{miles}{hour}*\frac{1hour}{3600seconds}*\frac{5280ft}{1mile}=880\frac{ft}{seconds}

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

distance=speed*time\\\\distance=880\frac{ft}{seconds}*10seconds=8800ft

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

Have a nice day!
