an air force plane left nairobi and flew west at an average speed of 159 mph. a cargo plane left sometime later flying in the same direction at an average speed of 207 mph. after flying for 5.3 hours the cargo plane caught up with the air force plane. find the number of hours the air force plane flew before the cargo plane caught up.
show all work, -

The air force plane travelled for a total of 6.9 hours.

SOLUTION:

Given, An Air Force plane left Nairobi and flew west at an average speed of 159 mph.  A cargo plane left sometime later flying in the same direction at an average speed of 207 mph.  After flying for 5.3 hours the cargo plane caught up with the Air Force plane.  

We have to find the number of hours the Air Force plane flew before the cargo plane caught up.

Now, we know that,

For air force plane

Now, when cargo plane caught the air force plane the distance travelled by the planes will be equal.

So,

Time taken by air force plane = 6.9  hrs

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
