Total number of hours she schduled to play the game = 3
hours.
Let us convert mixed fraction into improper fraction

Duration of each round =
.
In order to find the number of rounds Nicole can play, we need to divide total number of hours by duration of each round.
÷ 
Converting division sign into multiplication flips the second fraction.

Crossing out 12 by 4, we get 3 on the top of second fraction.


Because problem is about number of rounds.
So, total number of round would be 5.
Um, is there angles to look at, or an actual problem?
Answer:
I am only a 7th grader so I will probably get this incorrect but I think the correct answer is A.
Step-by-step explanation:
We breakdown the components of the distances.
(1) 90 miles west.
x - component = -90 miles
y - component = 0 miles
(2) 80 miles, northwest (120°)
x - component = (80 miles)*(sin 30°) = 40 miles (negative)
y - component =(80 miles)*(cos 30°) = 69.282 miles (positive)
Solve for the distance,
√(-90 - - 40)² + (69.282 miles)² = <em>147.31 miles</em>
