Last year, Tim rode his bike a total of 50 3/8 miles. This year, he rode his bike a total of 258 3/4 miles.
Which of the following explains about how much farther Tim rode his bike this year than last year?

A. About 200 times farther; Subtract last year's distance from this year's distance to get 208 3/8. Then round to the nearest hundred to get 200.

B. About 50 times farther; Round each distance to the nearest whole number.
Then multiply last year's distance by 50 to see that 259 is close to 50 x 5.

C. About 10 times farther: 258 is about 5 times 50,and 3/4 is 2 times 3/8, so multiply 5 x 2 to get 10.

D. About 5 times farther, Round each distance to the nearest whole number.
Then multiply last year's distance by 5 to see that 259 is close to 50 x 5.
