Question

a A plane flies 1,620 km in 4 hours. What is the average distance it fleis per hour ?​

Answer 1

Answer:

Solution: 405km

Step-by-step explanation:

Given: Distance= 1620km

         : Time taken= 4 hours

To find the average distance the plane flies in an hour first we need to find the average speed of the plane. As we know,

⇒ Average speed= Distance travelled/ Total time taken

   Average speed= $1620/4=405kmph$

405 km/ hour refers to the the distance travelled in an hour

∴ Average distance= $405km$

This also proves the fact that average speed is equal to the average distance travelled in 1 hour.
