something is wrong

given car covers 45*1160 yards in 3600 secs, so it will take T= (22 * 3600)/45*1160 secs which ends up in 44/29 secs.
which is not in the given answer choice.

By the way, 1 mile = 1760 yards , with this it takes 1 sec to cover 22 yards.

Unfortunately, I don't know the solution. I know only the OA. This question is similar to the other one that I posted under "farmer". I got them in the INternet. There should be some tips to solve them not just the simple calculation
