It should be 22*3600/45*1160
22/45 is aprox equal to 1/2
3600/1160 is aprox equal to 3
Answer should be 1.5 sec.
What is the source of this question?

using 1 mile = 1100 yds simplifies a bit

(22/1100) = miles = 2/100 = 1/50
(45/3600) = miles per second = 5/400 = 1/80

(1/50) / (1/80) = 8/5 = 1.6

does not matches with any of the choices ???

Old post, but just in case someone stumbles upon this question as I did, there is the following error:
According to wikipedia (generally a good source) 1 mile is 1760 yards, not 1160 as per the question. The answer would then be 1 second, even though that is not one of the answer choices.

If it reads, "how many seconds", then it is advisable to take everything in yards per second

1 mph is equivalent to 1160/3600 yps

�45 mph is equivalent to 45 × 1160/3600 yps

Or 45 × 1160 yards in 3600 seconds

Or 22 yards in [(22 × 3600)/ (45 × 1160)] seconds, i.e. nearly [spoiler]1.5 seconds[/spoiler].

But that's true for some temporary assumption if taken on test ever, because there are 1760 yards in a mile, not 1160. Moreover, no choice is still fitting to my answer, anything underhanded?
