Cruise Speed (Normal)473 knots. Cruise Speed (Normal). Compared to the average Turbofan-powered Narrow-body Commercial Passenger Plane, which cruises at 458 knots (527 mph) to maximize range and can cruise at a maximum speed of 472 knots (543 mph), the Bombardier CRJ700: 1  Maximizes its range at a 11 knot (13 mph) lower speed (a 2.4% margin).
3. Velocity. Now let's build on this for a minute. Generally, 14 year old average cruising speed would be about 65 mph. Average freshman pitcher (14 to 15 year old) cruising speed would be about 70 mph. Average cruising speed for a good high school pitching prospect at 14 to 15 years old would be about 75 mph.That will usually get a freshman pitcher onto the JV team, assuming reasonable pitching ability to go along with the pitching velocity. Cruising at 80 mph as a freshman would be a potential star.verage cruising speed for a good high school pitching prospect at 14 to 15 years old would be about 75 mph.
