Algebra
Solution:
Step 1.
Let x = Distance Traveled (in miles)
Step 2.
Then, using Equation 2-14,
= Time Taken by Faster Plane (in hours)
x
525
= Time Taken by Slower Plane (in hours)
x
350
Step 3.
Time Taken by Faster Plane = Time Taken by Slower Plane - 2

350x = 525x - 367,500
350x - 525x = -367,500
-175x = -367,5000
