Question

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?

Answer 1

The answer is 240. 78+54+108

Answer 2

240 miles

Explanation:

An estimate is a rough calculation of value in using a given data.

First day's trip = 78 miles

Second day's trip = 54 miles

Third day's trip = 2(54)= 108 miles

Estimate of the total trips = 78+54+108 miles.
