Answer 2

Thus, on Sunday Mr. Cohen will drive
`84(22)/(10)=86(1)/(5)` miles.

Explanation:

Given : Mr.Cohen drives
`84(2)/(10)` miles on Tuesday,
`84(6)/(10)` on Wednesday, and 85 miles on Thursday.

Here, distance traveled by Mr. Cohen on Tuesday =
`84(2)/(10)=84(1)/(5)`

distance traveled by Mr. Cohen on Wednesday =
`84(6)/(10)=84(3)/(5)` miles

distance traveled by Mr. Cohen on Thursday =
`85=84(5)/(5)` miles

On Every day an odd multiple get multiplied like on Tuesday it is 1 , Wednesday its 3 , Thursday its 5 so for for Friday multiply by 7, for Saturday multiply by 9 and for Sunday multiply by 11.

Similarly, on friday he will covers a distance of
`84(7)/(5)=84(14)/(10)=85(2)/(5)` miles

on Saturday he will covers a distance of
`84(9)/(5)=84(18)/(10)=85(4)/(5)` miles.

on Sunday he covers a distance of
`84(11)/(5)=84(22)/(10)=86(1)/(5)` miles.

Thus, on Sunday Mr. Cohen will drive
`84(22)/(10)=86(1)/(5)` miles.
