A bicyclist was on a 4 day tour. On the first day, he rode 14 miles. On the second day, he rode 41 miles. On the third day, he rode 78 miles. And on the fourth day, he rode 121 miles. Estimate how many miles he rode in total. From the choices below, select the student with a more reasonable solution.
Student A: I think he rode about 230 miles. I rounded 14 to 10, 41 to 50, 78 to 70 and 121 to 100. Then I added 10, 50, 70 and 100 to get an estimate of 230 miles.
Student B: I estimate he rode around 255 miles. I added 14 and 41 to get 55 and then I estimated 78 and 121 as 200. Then I added 55 and 200 to get 255
