This is a SHRINKING GAP question.
Train A traveled at 35 miles per hour and Train B traveled at 25 miles per hour,
35 mph + 25 mph = 60 mph
So, the gap CLOSES at a rate of 60 mph
Train A and Train B began traveling towards each other from opposite ends of a 500-mile long track at 1:00 PM
We need to reduce the gap from 500 miles to 0 miles
In other words, we must close the gap a total of 500 miles
At what time did the trains meet?
time = distance/rate
= 500 miles/60 mph
= 50/6
= 25/3
= 8 1/3 hours
= 8 hours and 20 minutes
So, if the trains started at 1:00 pm, then the time the trains MET = 1:00 pm + (8 hours and 20 minutes)
= 9:20 pm
Answer: E

Brent
