Is a biologist who is measuring the length of salmon as they travel upstream collecting qualitative data true or false?
True.
In still water a boat can travel four times as fast as the current in the river A trip up the river and back which totaled 150 km took 8h Find the speed of the current?
Call the unknown speed of the current c and the speed of the boat in still water b. When travelling upstream, the net speed of the boat will be b - c and when travelling downstream the net speed of the boat will be b + c. Since b = 4c, the speed upstream will be 3c. The distance upstream is one-half the total travelling distance of 150 km or 75 kilometers. Distance travelled = speed X time at speed, so that upstream time = 75/3c, downstream time = 75/5c, and the sum of these is the total time stated to be 8 hours. Thus 75/3c + 75/5c = 8. Multiplying both sides by 15c yields 75(5 +3) = 120c, or c = (8 X 75)/120 = 5 kilometers per hour.

A jogger travels at a speed of 5 mile and seconds for one miute How fast would he or she travel in5 miles and seconds?
A jogger travels at a speed of 5 miles and seconds for a minute. How far would he or she travel in that time
Riverboat with a stream powers engine that could travel up-or downstream?
A riverboat with a steam powered engine that could travel either upstream or downstream was called a steam boat.
Does a river travel upstream or down?
By definition all rivers run downstream, with the possible exception of tidal effects where the river meets the sea (as the tide comes in, in some places the water may run "backward" up the river for a usually short distance).
What directions do koi fish swim?
Anything with a face should be looking inward and almost never outwards, and with Koi, they ALWAYS go upstream and never downstream.
Riverboat with a stream powers engine that could travel up or downstream?
A steamboat is a riverboat with a steam powered engine that could travel up or down stream.
What is a lock aka water transport?
a lock is a system that allows ships to travel upstream and down stream
What border does the jet stream travel between?
The jet stream travels between hot and cold air.
Where might someone travel by using the gulf stream?
the gulf stream originates in the carribean/ gulf of Mexico and travels across the Atlantic ocean to northern Europe.
What statement BEST summarizes where Pacific Salmon spend their lives?
they spend all their lives in the very same river or stream, but they always travel upstream to lay their eggs late in life
Why did the steam engine improve travel on rivers and canals?
it was easier to travel upstream
What made river travel more reliable and upstream travel easier?
steamboats
How do bedouins travel?
they travels travel in differebnt travels to get get places
Why can river not be used for transportation in Nepal?
two reasons - rapid flow and it cascades down through the rocks - so boat can travel up stream - river are only good for downstream rafting in nepal
