Diego walks at a rate of 3.7 miles per hour and Elena walks 4.3 miles per hour.
While they are walking, Elena's dog run back and forth between the two of them at a rate of 6 miles per hour.
Assuming the dog does not lose any time in turning around, how far has the dog run by the time Diego and Elena reach each other?
:
Find the time (t) it takes for them to meet
Write a distance equation, dist = speed * time
When they meet, the sum of their distances = 2mi
3.7t + 4.3t = 2
8t = 2
t = 2/8 or 1/4 hr or 15 min
:
the dog was running for 1/4 hr at 6 mph * 6 = 1.5 mi the dog ran
