Question

during five succesive hours a car covered 45 km 52 km 48km 40 km55 km find the average distance of the car per hour

Answer 1

hey friend!

The answer to your question is here!

To find average of anything follow this formula:

Average (Mean)= sum of all observations/number of observations.

here the data is given that a car covers given km each in an hour so there are 5 hours and there is a figure of km covered in each hour.

Now lets use this average formula and find out the answer!
 
Average= sum of all observations/number of observations
      
             = 45+52+48+40+55/5
             = 240/5 
             =48 km

So, the average distance covered by the car per hour is 48km
