A histogram shows the frequency of data within different ranges
A dot plot is generally used with the exact data values listed along an axis and a dot for each data value above the axis. Then the exact data values can be read from the dot plot.

The resultant velocity of the plane is the sum of the two velocity vectors which are perpendicular to each other. See the attached figure.

The magnitude of the resultant velocity is

$\sqrt{160^2+30^2}= \sqrt{26500}=162.79 \;mph$ .
