Answer 2

Calculation of Average Speed

To calculate the average speed for the entire journey, we need to determine the total distance traveled and the total time taken.

The car first traveled 4 km at a speed of 44 km/h. It then made a stop for 11 minutes, which is equivalent to 11/60 = 0.1833 hours. After the stop, the car traveled an additional 2 km in 100 seconds, which is equivalent to 100/3600 = 0.0278 hours.

To calculate the total distance, we add the distance traveled before and after the stop: 4 km + 2 km = 6 km.

To calculate the total time, we add the time taken before and after the stop: 0.1833 hours + 0.0278 hours = 0.2111 hours.

Now we can calculate the average speed by dividing the total distance by the total time:

Average Speed = Total Distance / Total Time

Average Speed = 6 km / 0.2111 hours

To convert the average speed to km/h, we multiply it by 60:

Average Speed = (6 km / 0.2111 hours) * 60

Calculating this, we find that the average speed for the entire journey is approximately 170.1 km/h.

Please note that this calculation assumes a constant speed during each segment of the journey and does not take into account any other factors that may have affected the car's speed.
