One year ago, Nolan could run a mile in m minutes. Since then, his time has decreased by 9%. Write two different expressions that represent the number of
minutes it now takes Nolan to run a mile and stow or explain why the expressions
are equivalent.

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

i dont know men

step-by-step explanation:

answer: 414,377,008

step-by-step explanation:

just multiply it

60: 45 =12: 9 =4: 3 so the answer is 4: 3
