1) A plane whose airspeed is 220 km/h heads due north. It suddenly encounters a 150 km/h cross wind
blowing due east. What is the resulting velocity of
the plane with respect to the ground?

There is no graph to look at on here, but i shall explain them to you. a line graph is just in its title it’s a graph with a line running through the dots to show an increase or decrease. a bar graph is used to show how much or how little something is so a comparison. a scatter plot is used to graph points to tell the data. and i don’t know what a histogram is.
