The average number of kms Ekta a needs to run on the remaining days( 6th to 7th day)  of the week to achieve the weekly average target of 12 kms per day is  24 km.

Step-by-step explanation:

Given:

An average of 12 kms per day  Ekta has  to run to keep herself prepared for the marathon race.

Total of 36 kms over the first 4 days was run by Ekta and could not run on the 5th day.

Average weekly target of 12 kms per day.

To Find:

The average number of kms  Ekta needs to run on the remaining days of the week to achieve the weekly average target of 12 kms per day.

Formula Used:                    

Average = Sum of Values/Number of Values                  

Solution:

As given- An average of 12 kms per day  Ekta has  to run to keep herself prepared for the marathon race.

Total of 36 kms over the first 4 days was run by Ekta and could not run on the 5th day.

Average weekly target of 12 kms per day.

 1st  to 4th  days distance run= 36 km

  5th  day distance run =0 km            

Weekly Average of distance run = Sum of distance run on week’s day /Number of  week day  

Weekly Average of distance run  =  (1st  to 4th  days distance run +5th  day distance run+ 6th to 7th days distance run) / Number of  week days  

12 = (36+0+ 6th to 7th days distance run)/7

84=36+6th to 7th days distance run

48 km = 6th to 7th days distance run

Therefore, Average of 6th to 7th days distance run = 6th to 7th day distance run/ Number of days                                                                            = 48/2

= 24 km

Thus, The average number of kms Ekta a needs to run on the remaining days (6th to 7th day) of the week to achieve the weekly average target of 12 kms per day is    24 km.
