Abird is about 6.26.2 in. long, with a thin, dark bill and a wide, white wing stripe. if the bird can fly 9292 mi with the wind in the same time it can fly 6060 mi against the wind when the wind speed is 44 mph, what is the rate of the bird in still air?

mph

Explanation:

= Speed of bird in still air

= Speed of wind = 44 mph

Consider the motion of the bird with the wind

= distance traveled with the wind = 9292 mi

= time taken to travel the distance with wind

Time taken to travel the distance with wind is given as

                             eq-1

Consider the motion of the bird with the wind

= distance traveled against the wind = 6060 mi

= time taken to travel the distance against wind

Time taken to travel the distance against wind is given as

                             eq-2

As per the question,

Time taken with the wind = Time taken against the wind

mph

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
