Calculate the average delay in the time of arrival of train

Answer 1

Explanation:

As per question,

It is told that -

Correct time of arrival of a Dehradun Shatabdi train at New Delhi station is 8 A.M....

Monday arrival time = 8:10 A.M.

Tuesday arrival time = 8:30 A.M.

Wednesday arrival time =7:45 A.M.

Thursday arrival time = 7:55 A.M.

Friday arrival time =8:00 A.M.

Saturday arrival time = 8:05 A.M.

Sunday arrival time = 7:50 A.M.

Now...

Delay days = Monday, Tuesday and Saturday.

Total delay time =

Monday - (8:10-10) = 10.

Tuesday - (8:30-30) = 30.

Saturday - (8:05-5) = 05.

Total = (10+30+05)

= 45.

Average = 10+30+5/3

Or,

45/3

= 15.

Thus,the average delay in the time of arrival of train is 15. ANS...
