Two towns are #145# #km# apart. A bus leaves one of the towns travelling at #60# #kmh^-1# toward the second town and a car leaves the second town travelling at #90# #kmh^-1# toward the first. How far apart are the bus and the car after half an hour?

The car would travel #90# #km# in 1 hour, so it will travel #45# #km# in half an hour #(30# #min)#. The bus will travel #30# #km#. They have traveled a total of #75# #km# of the #145# #km# between the towns, so there is #145-75=70# #km# between them.
