The speed during the first hour is the slope of the piece of line that shows the first hour on the graph.

Average speed is always=(distance covered)/(time to cover the distance)

Distance covered during the first hour = from 0 miles to 40 miles on the graph; that's 40 miles.

Time to cover the distance = from 0 hours to 1 hour on the graph; that's 1 hour

Average speed = (40 miles) / (1 hour)

Average speed during the first hour = 40 miles/hour

I love you too.
