Alexander and Judy are 31 miles apart on a calm lake paddling toward each other.
Alexander paddles at 5 miles per hour, while Judy paddles at 8 miles per hour. How long will it take them to meet?
Assuming that they left at the same time: Distance = rate*time
Let t = time in hours
Alexander's distance: 5t
Judy's distance: 8t
total distance: 31
5t%2B8t=31
13t=31
t=31%2F13
t= 2.3846 hours
or
t= 2hrs+60(.3846)mins
t=2hrs and 23 mins
Barring any fatal careless errors, that should be it.
Happy Calculating!!!
