Final answer:
To calculate the average speed of Anna and Bob on each day, divide the total distance traveled by the total time spent driving. Therefore, the average speed on the first day is 68 miles per hour and on second day is 66 miles per hour.
Step-by-step explanation:
To find the average speed of Anna and Bob on each day, we can use the formula:
Average Speed = Total Distance / Total Time
On the first day, Anna drove for 2 hours and Bob drove for 3 hours, so the total time is 2 + 3 = 5 hours. The total distance they traveled is 340 miles. Therefore, the average speed on the first day is 340 / 5 = 68 miles per hour.
On the second day, Anna drove for 4 hours and Bob drove for 1 hour, so the total time is 4 + 1 = 5 hours. The total distance they traveled is 330 miles. Therefore, the average speed on the second day is 330 / 5 = 66 miles per hour.
