Question

a car travelling at an average speed of 100 km/h covers a certain distance in 3 hours. at what average speed must the car travels to cover the same distance in 2 hours​

Answer 1

Needs to have an average speed of 150km/h

Explanation:

With the current average of 100 km/h in a 3-hour span, you would cover 300km. Since you want to cover that same amount (300km) in 2 hours all you do is 300/2 which is 150. Meaning you need an average speed of 150 km/h
