greetings

the answer is D

3/5 = 9/15

1/3 = 5/15

9+5= 14

Step-by-step explanation:

D

Step-by-step explanation:

find the common denominator by finding the least common multiple of the two denominators

3/5 * (3) = 9/15

1/3 * (5) = 5/15

add both and u get 14/15

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
