You need to change your mph to inches per second. In order to change miles to inches, first multiply by 5,280 to change to feet, then multiply by 12 to get to inches. After that, change the hours to seconds by dividing by 60, and then by 60 again (the first time changes it to minutes, then the second time changes it to seconds). After you do all that, you should come up with an answer of 1715.824 inches per second.
Since you know the plate is 17 inches long, you should set up a proportion to solve: %281715.824%2F1%29+=+%2817%2Fx%29. Solve the proportion to get your answer, which is .0099 seconds.
