The speed of light in a vacuum is 2.998 ã 108 m/s. what is its speed in miles per minute (mi/min)?

Simply divide the speed of light by 1000 to get klm/sec
next divide the klm/sec by 1.6 to get miles/sec.
next multiply miles/sec by 60 to get miles per minute

= 11,242,500 miles/min
= 11,240,000 miles/min (with significant figures)

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
