B) 0.36 m/s

C) 0.47 m/s

D) 0.67 m/s

An airplane flies eastward and always accelerates at a constant rate. at one position along its path it has a velocity of 34.3 m/s, it then flies a further distance of 40100 m and afterwards its velocity is 47.5 m/s. find the airplane\'s acceleration and calculate how much time elapses while the airplane covers those 40100 m.

Jessie ran 5000 meters from the cops and an average speed of 6 meters / second before he got caught . how long did he run?
