How many hours did they travel during the first two days
bearhunter [10]
They travelled 3 and 5/6 miles, then drove 2 and 2/6 more the next day. To find the total, you must add them up. So...
3 \frac{5}{6}  + 2 \frac{2}{6}  = 5 +  \frac{7}{6}  = 6 \frac{1}{6}
They travelled for 6 and 1/6 hours, or 6 hours and 10 minutes.
