Question 874752: Provided: d = rt, where "d" is distance, "r" is rate, and "t" is time.
Two trains on the same track, initially 648 miles apart, leave from
their positions simultaneously. They are on a head-on collision
course. One train is traveling 35 mi/hr and the other is traveling
85 mi/hr. What is the length of time to impact?

35t + 85t = 648
120t = 648
t = 5 hours 48 minutes
