Question 782039: please help me solve this problem :Two high-speed ferries leave the same time to go to the same island. The first ferry, the cat travels at 31 miles per hour.the second the bird travels at 23 miles per hour. In how many miles will the two ferries be 24 miles apart ?

You can put this solution on YOUR website! I'm going to guess, is it 24?

Just kidding, assume you mean how far will the boats have to travel to be 24 mi apart
:
Their relative speed is 31 - 23 = 8 mph
Find the time to be 24 miles apart = 3 hrs
:
In three hrs:
1st boat will have traveled 3*31 = 93 mi
2nd boat will have traveled 3*23 = 69 mi
:
Check: 93 - 69 = 24 mi
