There is a boat stranded 21 miles from shore going towards the dock at 3mph.
The rescue bout is at shore ( which is 21 miles away ) heading towards the boat at 25mph.
How long will it be for the boats to meet up with each other?
:
Let t = time required for them to meet
:
Write a distance equation: Dist = speed * time
:
3t + 25t = 21
:
28t = 21
t = 21%2F28
t = 3%2F4 hr to meet
