Claire jogs 6 miles per hour and Megan jogs 5 miles per hour. They start together at their campsite and jog to an outpost 18 miles away. When Claire gets there, she immediately turns around and heads back towards Megan. How many miles will they be from the outpost when they meet? Express your answer as a mixed number.
Claire gets there in 3 hours
Megan stil has 3 miles to go
the two of them will cover those 3 miles (and meet) in 3 miles/ (6+ 5 m/hr)= 3/11 hr
at 6 m/hr claire will have travelled back from outpost : 6 m/hr * 3/11 hr = 18 /11 miles = 1 7/11 miles
