Question

Unless otherwise specified in the question, responses to numerical question must be within 5% of the correct answer. Try out different responses to the following question, which has an answer of 20, where a correct response is between 19 and 21. What is the average velocity (in kilometers per hour) of a cart that travels 100 km in 5 hours?

Answer 1

20 km/h

Explanation:The speed is calculated by dividing the distance traveled over the time used, both in the indicated unit. In this case we travel 100 km in 5 hours, then the average speed is 100 km/5h= 20km/h. Then the answer of the average speed is exactly 20 km/h, even though during that time it could travel at different speeds, in total at the end it was traveled in average 20 km per hour.
