Problema Solution
two cars leave the same town at the same time. one travels north at 60 mph and the other south at 45 mph. in how many hours will they be 420 miles apart?
Answer provided by our tutors
Let 'd' stand for the distance car 1 travels, '420-d' stand for the distance car 2 travels, and 't' stand for the number of hours this takes. We can write:
Car 1
d=60t
Car 2
420-d=45t
Using Algebrator to solve for t and d, we get:
d=240 miles
t=4 hours
