Question

Hua 13. A car travelling at an average speed of 100 km/h covers a certain distance in 3 hours 20 minutes. At what constant speed must the car travel to cover the same distance in 2 hours and 40 minutes? (2)​

Answer 1

Salut/Hello!

Answer: 133 km/h

Explanation:
We need to first find out the distance travelled in 3 hours and 20 minutes.
We can say that 3 and 20 minutes is 3.20 by knowing that 100 km/h results that the distance travelled is 320 km

The same distance in 2 hours and 40 minutes:
We can say 2 hours and 40 minutes is 2,40 and we know our distance is 320 km results that the speed will be approximately 133 km/h
