Multiple Chuine 1 point The fastest airplane is the Lockheed 5R.71 Ula:khird a high-sititude spy plane-first built in 2964. If an SR-71 is clocked traveling 15.km west in 15.35, what is its average volocity in kilometers perhour? 3529km/hr 806km/hr

To find the average velocity of the SR-71, we need to divide the distance traveled by the time taken.<br /><br />Given information:<br />- Distance traveled: 15.35 km<br />- Time taken: 15.35 seconds<br /><br />Step 1: Convert the time from seconds to hours.<br />15.35 seconds = 15.35 / 3600 hours = 0.00429 hours<br /><br />Step 2: Calculate the average velocity.<br />Average velocity = Distance traveled / Time taken<br />Average velocity = 15.35 km / 0.00429 hours = 3569.5 km/hr<br /><br />Therefore, the average velocity of the SR-71 is 3569.5 km/hr.<br /><br />The correct answer is $3529km/hr$.
