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.
