Hii Mate Here is Your Answer,
Let his usual speed be x
Today speed is = 7x/11
Total distance be Y for all cases.
The time used the person for today is 22hrs given.
Time = distance/ speed
= 22 = y/7x/11
22=11y/7x
Y= 154X/11= 14X
Y= 14X. ....... Eq.1
Now for normal speed X the distance is remain same Y
Time = Y/X.
14X/X From eq.1
=14
Your Answer is 14hrs.
Hope this helps You a lot ........
