How many miles did John drive on the first leg? ** The first leg was 200+10=<<200+10=210>>210 miles
How many hours did John drive on the first leg? ** So he drove 210/70=<<210/70=3>>3 hours
How many hours did John drive on the second leg? ** The second route took 240/80=<<240/80=3>>3 hours
How many hours did John drive in total? ** So in total he drove 3+3=<<3+3=6>>6 hours
