Two trains leave the station at the same time, one heading west and the other east. the westbound train travels 18 miles per hour faster than the eastbound train. if the two trains are 800 miles apart after 4 hours, what is the rate of the westbound train? do not do any rounding. this has to be right, the first time because it will force me to start over

The combined speeds of the trains equals 800 miles per 4 hours or

200 miles per hour.

This averages out to 100 miles per hour for each train.  

Westbound train is 18 mph faster so  

109 mph = Westbound

91  mph = Eastbound

That seems to be right except trains speeds of 91 mph and 109 mph seem to be VERY fast.

Step-by-step explanation:

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
