Ih took Joseph 30 minutes longer to drive 375 km from along the north shore of a riverfrom Apex to Rounder than it took to return along the south shore, a distance of 420 km.On the retum trip the highway was wider and in better condiftion, so he was able toaverage 10 km/h faster. What was his average speed on cach part of the trip?
