3. T EAM MEMBER E STIMATES KyleEthanDustin 240 Miles640 Miles480 Miles

4. M ETHOD /A PPROACH First we estimated the average speed of the raft. We then estimated how many hours would be spent each day rafting. We used the information to calculate the miles per day. Then we multiplied that by the number of days to get the total distance.

5. A SSUMPTIONS Traveled entire canyon in raft. Traveled constant speed. Traveled 3 hours a day. Speed was 5 miles per hour. Traveled same distance and time every day.

6. S OLUTION (5 miles/hour)(3 hours/day) = 15 miles/day (15 miles/day)(16 days) = 240 miles.
