Circle A or +2

Step-by-step explanation:

Step 1. Cross Multiply

This gets you -15 * -2 and -16 * -1

Step 2. Simplify

This gets you 30/16 which converts to 15/8 or 1 7/8

Step 3. Round your answer to the nearest whole number

This would result you with positive 2

Step 4. CIRCLE A :)

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
