The bar graph shows the lengths of the longest rivers in the United States. A. About how long is the Mississippi river
B. Tell which rivers have the same length and approximate that length

A. Mississippi river lands on the 2.4 part of the graph. Since it represents by thousands of miles, the Mississippi river measures about 2,400 miles.

B. From the graph, St. Lawrence and Rio Grande are about the same in terms of bar length. They land close behind 2, so they would approximately measure 1.9 or 1,900 miles.
