Last year, Tim rode his bike a total of50 3/8 miles. This year, he rode his bike a total of 258 3/4 miles. Which of the following explains how much farther Tim rode his bike this year than last year? A. 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. 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 × 5.

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

D. 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 × 5.
