The sum of 2 numbers is 60. one number is four times as large as the other. what are the numbers?

12 and 48

Step-by-step explanation:

let one number be x then the other number is 4x ( 4 times larger )

the sum of the 2 numbers is 60, thus

x + 4x = 60

5x = 60 ( divide both sides by 5 )

x = 12

the 2 numbers are x = 12 and 4x = 4 × 12 = 48

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 think the answer is .36

what i did was only 2.88 divided by 8
