1 answer:
Alright! First you'd subtract the amount of the part ($44) from your total ($179), then you'd divide by the rate of cost ($45). Your equation would be: ($179 - $44) ÷ $45 = h. Then you solve: ($179 - $44) = $135 ($135 ÷ $45) = 3 h = 3. The answer is 3 hours.

Lets say the race is x km long.
That means she ran 65% of x.
And that also means that 65% of x = 3
So 65%*x=3
65/100x=3
x=3*100/65
x=300/65
x=4.62
