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.
