A bicyclist was on a three day tour around a lake. On the first day, he rode 78
miles, on the second day he rode 54 miles, and on the third day he rode twice
as far as the second day. Which of the following is a good estimation of how far he rode in the three days?

A. 190 miles
B. 230 miles
C. 270 miles
D. 310 miles
E. 350 miles

B. 230

Step-by-step explanation:

On the first day since he rode 78 miles we just have 78

Then on the second day he rode 54, then twice as much on the third day than the second. ( 54 times 2 = 108 )

Add 78 + 54 + 108 = 240 ( estimate is 230 )
