Question 885103: Two objects are traveling in opposite directions. One is traveling three miles per hour faster than the other. In two hours, they are four hundred and two miles apart. How fast is each object traveling? Answer by JulietG(1812) (Show Source):
You can put this solution on YOUR website! In one hour, the objects are 201 miles apart (402/2)
A + B = 201
A = B+3
Substitute the known value of A from the second equation into the first.
A + B = 201
(B+3) + B = 201
2B + 3 = 201
Subtract 3 from each side
2B = 198
Divide each side by 2
B = 99
.
The slower object is traveling 99 mph; the faster, 102 mph
Add them together and they are traveling 201 mph
201 mph * 2 hours = 402 miles
