Important: Please express fractions properly: use the " / " symbol to represent division. Your question should read:
"A Mallard duck flies 5/6 of a mile in 1/60 of a hour. Find the rate (speed) at which it flies."
To do this, divide the distance flown by the elapsed time:
5
5/6 mile -----
----------------- = -------6------------- miles / hr
1/60 hour
1
-----
60
to divide 5/6 by 1/60, write 5/6 and multiply that by the reciprocal of 1/60.
In other words, write 5/6, invert (1/60) and then multiply.
This comes out to (5)(60)
---------- mph
(6)(1)
Do not multiply here. Instead, reduce 60/6 to 10/1.
Can you now write out the final answer, in mph? (miles per hour)
