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.
