Thread: Grade 11 Word Problem

A biathlon event involved running and cycling. Kim can cycle 30km/h faster than she can run. If kim spends 48 minutes running and a third as much time again cycling in an event that covers a total distance of 60 km, how fast can she run?

I also have a test on these type questions next week, if someone could explain how to do them or post a site with practice questions that'd be nice, thanks!
