Comment

This is a good question to estimate the answer. That will get rid of the ones you don't have to check - maybe.

123 miles in 3 hours = 123/3 = 40 about Too far away. Not answer

96 miles in 3 hours = 100 / 3 = 33 about. This is one you should check.

288 miles in 9 hours = 270/9 = 30 about. Another one to check

66 miles in 3 hours = 66/2 = 33 Not right.

310 miles in 10 hours = 310/10 = 31 Not right

Some of these do not need to be rounded to get the answer. If the division is the same as the question and it does not come to 32 then it will not be included in the answer.

B gives 32 miles / hour. B is one of the answers

C gives 32 miles / hour. C is one of the answers.
