Answer 1

Jennie's average speed for her vacation drive is calculated by dividing the total distance traveled, 195 km, by the time taken, 5 hours, resulting in an average speed of 39 km/hr.

Step-by-step explanation:

To calculate Jennie's average speed for her vacation drive, we utilize the formula for average speed, which is the total distance traveled divided by the total time taken. The formula for finding the average speed (Vavg) is represented by:

Vavg = distance / time

Given that Jennie drives 195 km over a period of 5 hours, her average speed is calculated as follows:

Vavg = 195 km / 5 h = 39 km/hr.

Therefore, the correct answer is option A. 39 km/hr.
