Problema Solution
two planes start from the same airport and fly in opposite directions. the first plane s flying 40 miles/hour faster than the second plane. in 5 hours the planes are 2000 miles apart. find the rate of the slower plane.
Answer provided by our tutors
Using the general equation d=rt (distance=rate*time), we can write:
Plane 1:
x=(r+40)5
Plane 2:
2000-x=r5
Using Algebrator to solve for r, we get:
r=180mph
This is the rate of the slower plane.
