If these birds travel on an average speed of 350 km/ day, find out in how many days each of the species will take to complete the round trip.

The great snipe is the fastest known migratory bird. Scientists found that the bird can fly non-stop for approximately   miles  . If the bird's speed is an average of   kilometers per hour  , how many hours can the great snipe fly without stopping?(Round the answer to the nearest tenth.   kilometer   miles)

As a crude approximation, we assume that the (constant) speed at which the birds make theirjourney increases linearly with the time they spend foraging for energy before commencing it,through the following formula:v0 = 50 + 3 τ, (8)where τ is the time in days that the red knot spends foraging in the Dutch Wadden Sea and v0 isthe constant speed in km per day at which it will be able to travel the entire journey of 9000 km.(b). Explain that the total time before the red knot arrives in South Africa will be given byT = 900050 + 3 τ + τ.

A bird, when travelling at its normal speed, takes nine hours more to travel 15 km against the wind than the time it takes to travel the same distance along the direction of the wind. If it doubles its speed and travels the same distance, it takes one and a half hour less when it flies along the direction of the wind than the time it takes to fly against the wind. Find the speed of the wind.2 kmph kmph kmph kmph

The leopard ends up 14 km west of its starting position. The trip takes 2 hours.Calculate the leopard's average velocity.

Rahul & Simran are at a distance of 1200 m. They start towards each other with speeds of 23kmph & 28kmph. As they start, a bird sitting on the cap of Rahul, starts flying towards Simran, touches Simran & then returns towards Rahul & so on, till they meet. What is the distance (in m) travelled by the bird, if its speed is 204 kmph?
