Test 9 Question 39.

A jet plane travels 600mph, while it takes a snail one hour to travel 1 foot, how many times faster, to two places of accuracy, does the jet plane travel than the snail? (1 mile= 5280 feet)

a) 3200
b)320
c)600
d) 3,200,000
e) 320,000

answer is c) but I'm getting d).

Any explanation?

How can the answer be c if that is the only answer without "two places of accuracy?" I am getting d as well :
600mph*5280=3168000 or 3200000ft/hr
Then divide that by 1ft/hr

Could it be a typo do you think?
