Abird flies from the south pole to the north pole. part of the journey is 1000 miles that takes 2 weeks. what is the bird’s velocity in that time? show work for credit and include final units.

The correct answer to the question is : 2.976 miles/hour.

CALCULATION:

As per the question, the distance travelled by the bird X = 1000 miles.

 The time taken by the bird to cover that distance t = 2 weeks.

                                                                                     = 2 × 7× 24 hours

                                                                                     = 336 hours

We are asked to calculate the speed of the bird.

The speed of the bird is calculated as -

                         speed v =

                                        =

                                        = 2.976 miles/hour                   [ans]

Hence, the velocity of the bird is 2.976 miles/hour.

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
