Journey 1: The travel starts at 30 mph for two hours, after which there is a rest of two hours. The journey then continues slightly faster, at 40 mph for one hour. Then it is time for another rest of one hour. At this point we are 100 miles from home. We return home after two hours of traveling at 50 mph.
