Average speed question! Help!

Satellite data taken several times per hour on a particular albatross showed travel of 1350 km over a time of 1.5 days.
Given these data, what was the bird's average speed in mph ?

1350km/1.5days=900km/day=900km/24h=37.5k…

1km=0.621371192 miles

37.5km/h=37.5(0.621371192)mi/h=23.3014…


10 points please.. i could really use it

Assuming you need NAUTICAL miles per hour (it is an albatross we're talking about...)
1350 km equals 1350 km /1.852 km/mile = 728.9 miles
It covers this distance in 36 hours.

So its average speed is

728.9 miles / 36 h = 20.2 mph.


If you want the albatross to fly over land (and use land miles as your measure of distance, use 1 km = 1//1.6 miles.

1 mile = 1.609344 km
=> 1 km= 1/1.609344 mile
=> 1350 kms= 1350/1.609344 miles
and 1 day= 24 hours
=> 1.5 days= 24*1.5=36 hours
So, average speed = 1350/(1.609344*36) mph = 23.3014... mph

v=(x/t)

therefore:
1350 km = 1350000 m
1.5 day = 1.5*24=36 hr

v=(1350000/36)=37,500 mph

edit: my bad i have calculated it with meters. the same thing with miles anyway.

1.5 days = 36 hours
1350 km = 839 miles

so we have 839 miles / 36 hours = 23.3 MPH
