Question 1194742

Suppose a driver with car leaves home at 8AM and first travels 30 km/hr for two hours, then stops one hour for coffee. He then travels at 80 km/hr for the next five hours, to arrive at the destination. (we imagine a magical car that does not need to accelerate or decelerate)

1. How many hours was this trip, from start to finish?

2. At what time did the driver arrive at the destination? 

3. How many km did the driver cover? 

4. what was the average <s><font color = red><font size = 4>rate of speed</s></font></font> rate/speed (including the rest time!), in km/hr for the entire trip?
<pre>Question 4 doesn't make sense, since the AVERAGE RATE/SPEED for the entire trip definitely DOES NOT INCLUDE rest time - as in the
time (1 hour) he stopped for coffee.
