Teds car is now worth $9000 which is 60% of what he paid for it. what did he pay for this car?

amount pay for car is $15,000

Step-by-step explanation:

given data

car worth = $9000

paid = 60 %

to find out

$9000 is 60% of what number

solution

we consider amount pay = x

now we get here amount to pay for this car is express as

  .............1

put here value we get

9000 = ( x ) × 0.60

x =

x = $15,000

so  amount pay for car is $15,000

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
