What is the decimal equivalent of 13/4?

3.25

hope this helped!!

3.25

Step-by-step explanation:

13 / 4 is an improper fraction . when you divide 13 by 4 you get 3.25

since the airplane is moving with constant speed then the distance travelled can be calculated by x=u*t

in km/h would be:

x=640*3.5=2.240 km

in m/s would be:

u=640 km/h= 640.000 m/h =640.000/ 3600 m/s =177.8 m/s

t= 3.5 h= 3.5 * 3600 s=12.600 s

then x=u*t= 177.8*12.600= 2.240.280 m

lockers 1, 4, 9, 16, 25, 40, and 49 are open
