I'm green river drift in Wyoming, ranchers bring their herd of cattle to the high desert to graze during the summer. The herd of cattle travels about 5.5 miles a day for 13 days to reach its destination. How far does the herd travel?

A. 143 miles
B. 71.5 miles

D. 65 miles

To find the total distance traveled by the herd of cattle, we multiply the distance traveled per day by the number of days:

Therefore, the correct answer is B. 71.5 miles.
