Answer:

810 minutes

13 hours 30 minutes

Step-by-step explanation:

Let the unknown value be x

5\:miles = 45 \: minutes\\90\:miles = x\:minutes

Sole the proportion for x ; Cross Multiply

5\times \:x =90 \times 45\\\\5x\: = 4050

Divide both sides of the equation by 5

\frac{5x}{5} = \frac{4050}{5} \\\\x = 810 \:minutes =\\13 \:hours \:30\:minutes

Aaron has a triathlon. Sunday he bikes 12 5/8 miles and swims 5 2/3 miles. Monday, he runs 6 3/8 miles. How many total miles Aar
Alla [95]
Let’s put these into one fraction each:

Biking:
= (12*5)/8 miles
= 60/8 miles
This can be reduced to,
= 15/2 miles

Swimming:
= (5*2)/3 miles
= 10/3 miles

Running:
= (6*3)/8 miles
= 18/8 miles
This can be reduced to,
= 9/4

Now we add all the distances up:
= (15/2) + (10/3) + (9/4)

Now we just can add the numerators and the denominators. We must find the lowest common factor (LCF) for our 3 denominators (2,3,4). Our LCF turns out to be 12. *Remember what we do to the denominator we must do to the numerator. So:
= (15/2) + (10/3) + (9/4)
= [(15*6)/12] + [(10*4)/12] + [(9*3)/12]
= (90/12) + (40/12) + (27/12)
= (157/12)
Therefore Aaron Ran 157/12 miles or 13.08 miles.

Hope this helps!

Pavlova-9 [17]
Part A. the origin is (0,0). Part B. the first point is right one and the down one and plot your point. 2nd one is left one and it is more than half so it is like a quarter of the square. the third point is, left 2 and it is less than 1/2 so it goes over a little less than 1/2.
