Jose needs to read 4 noves each month. LN be the number of novels Jose needs to read in M months.
we an equation relating N to M. Then use this equation to find the number of novels Jose needs to read in 17 months.

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

13.46

step-by-step explanation:

16.80 x .20 = 13.46
