Hi Roland2rule,
Let's take a look at your question.
There are some mistakes in the question.
The first one is that 1 mile = 1,760 yards not 1,160
and the options are listed incorrectly as well.
Let's solve the problem using 1 mile = 1,760 yards
The car is traveling at a constant rate of 45 miles per hour.
We need to find how many seconds will it take to travel a distance of 22 yards.
It means we need to convert 45 miles per hour to yards per second so that we have the same units.
Since,
1 mile = 1,760 yards and
1 hour = 3600 seconds, therefore,
45 miles per hour can be converted in yards per seconds as:
$$=\frac{45\times1760}{3600}=22 \text{yards per second}$$
Hence the speed of the car is 22 yards per second.
Now, we can easily see from the speed of the car that 22 yards can be traveled in 1 second.
The answer is
1 second.
The options are incorrect.
Hope it helps.
I am available if you'd like any follow up.
