It travels 100 miles in 2.5 hours.
Average speed = (total distance) divided by (total time) = (150 + 150) / (2.5 + 3.5) = 300/6 = 50 miles per hour.
The average speed is 2050/5 = 410 miles per hour.
The average speed of the plane that travels 3060 miles in 5 hours is 612 Miles Per Hour.
45 miles X 3 h = 135 miles. It will travel around 135 miles in 3 h.
