Using Figure 10, find the distance traveled if the average speed is 20 mph and the time
traveled is 40 minutes.
The line labeled A in Figure 10 connects 20 mph and 40 minutes. It passes through 14.5
Thus, the distance traveled is 14.5 miles.
Using Figure 10, find the time required to travel 31 miles at an average speed of 25 mph.
The line labeled B in Figure 10 connects 31 miles and 25 mph. It passes through
Thus, the time required is 70 minutes.
