Answer:
H) 0.75
Step-by-step explanation:
4.5 divided by 6 is 0.75
We don't use remainders in algebra for the most part.  We have to do regular division.  I'll try to show it here:
    
    ____._7___5_____________
6 ) 4    .    5     0
     4    .     2
  ____________
     0   .     3    0
     0  .      3    0

Answer:
Step-by-step explanation:
let wind velocity=x
speed of plane=y
(x+y)*4=808
x+y=808/4=202   ...(1)
(y-x)*4=488
y-x=122 ...(2)
add (1) and (2)
2y=202+122=324
y=324/2=162 
from (1)
x+162=202
x=202-162=40
wind velocity=40 m/hr
speed of plane=162 m/hr
