Try plotting the points on a graph, it might make it a bit easier to figure out an equation
300000 km/sec x 3600 sec/hr=1080000000 km/hr
1080000000 km/hr / 1.6 km/m=675000000 mph

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
