A car travels a total distance of 150km. At the 50 minutes mark the car has travelled 50km and at the 110 minutes the car has travelled 120km. Find the average velocity in metres per second of the car between the 50-minute mark and the 110-minute mark. Round the final answer to 2 decimal places

The average velocity is 19.44 m/s.

Step-by-step explanation:

The average velocity between two points can be calculated with the following formula:

The procedure is to calculate the difference for both distance and time, and dividing the two differences, we get the average velocity.

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
