Meg runs a 10-km race in 45 minutes (0.75 hours). what was her speed in kilometers per hour ? a. 7.5 km/hr b. 4.5 km/hr c. 13 km/hr d. 22 km/hr

My answer is opptionc, just check with anyone else

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.
