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 how much farther Tim rode his bike this year than last year?

A.

00:00

200 times farther; Subtract last year's distance from this year's distance to get 20838.

Then round to the nearest hundred to get 200.

B.

00:00

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.

00:00

10 times farther; 258 is about 5 times 50, and 34 is 2 times 38, so multiply 5 × 2 to get 10.

D.

00:00

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.
