Blood flows through a major artery at 1.2 m/s over a distance of 0.50 m, then at 0.70 m/s for another 0.50 m through a smaller artery.
1.) Is the average speed of the blood 0.95 m/s, greater than 0.95 m/s, or less than 0.95 m/s?
2.) Verify your answer to #1 by calculating the average speed.
Express your answer to two significant figures and include appropriate units.
