    Answer:

    1) 3:15 hours.

    2) 68 km per hour.

    Step-by-step explanation:

    Since a bus from Nantes at 3:50 p.m. and arrives at Tours at 7:05 p.m. after having traveled 221km, to calculate the journey time in hours and minutes and calculate the average speed of this bus, the following calculations must be performed:

    1) 7:05 – 3:50 = 3:15

         Thus, the duration of the trip was 3 hours and 15 minutes

    2) 0:15 = 0.25

        221 / 3.25 = X

        68 = X

        Thus, the average speed of the bus was 68 km per hour.
