She worked 8 hours
$60 / $7.50 (per hour) = 8 hours
Important: Please express fractions properly: use the " / " symbol to represent division. Your question should read:
"<span>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 </span>
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)
Ammar hikes 2.75 miles in 75 minutes so he hikes 2.75 miles in 1.25 hours. If you divide 2.75 by 1.25, you find his rate per hour: 2.2 miles per hour.

Answer:
c.) 38
Step-by-step explanation:
means "summation of the all the elements starting from the 3rd element to the 6th element".
The 3rd element in the series is 14, and the 6th element is 5; we have to add these and all the elements between them together.
∴ = 14 + 11 + 8 + 5
= 38
