An airline company purchased two new airplanes. One can travel at speeds of up to 600 miles per hour and the other at speeds of up to 720 miles per hour. How many more miles can the faster airplane travel in 12 seconds than the slower airplane?

0.4miles

Step-by-step explanation:

Given parameters:

Speed of A = 600miles/hour

Speed of B = 720miles/hour

Time of consideration  =  12seconds

Unknown:

The number of distance B travels over A = ?

Solution:

To solve this problem, we are going to find the distances both airplanes will cover within the given time.

  Distance  = speed x time

Convert the time from seconds to hours ;

                3600s  = 1hr

                   12s  =   = 0.0033hr

Distance that would be covered by A = 600miles/hour x 0.0033hr = 2miles

Distance that would be covered by B = 720 miles/hour x 0.0033hr = 2.4miles

The faster airplane will cover a distance 2.4 - 2.0 = 0.4miles than the slower plane

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.
