Answer:
20 mins.
Step-by-step explanation:
A babysitter charges a rate of $15 per hour. How long was the babysitter there if she makes $5?
x = hours she babysat
Equation:
15x = 5
Divide to isolate x:
15x = 5
/15 /15
x = 1/3 hrs.
Now, we convert into minutes, since she didn't work for a whole hour, to earn the $15
We know that there are 60 mins. in an hour
60 * 1/3
60/3
20 mins.
Therefore, the babysitter was there for 20 mins.
Hope this helps!
Volume is 216 sorry if you get it wrong
If you mean the price is now 120% of the original, $<span>4.74 (3.95 * 0.8) is the new price.
If you mean the price is now 80% of the original, $3.16 (3.95 * 1.2) is the new price.</span>
To solve this, we first have to find an individual rate:
3/5
4/7
For the first one:
1 lap in 5/3 minutes
Second one:
1 lap in 7/4 minutes
find a common LCD
5/3 and 7/4
20/12 and 21/12
4 laps in 7 minutes is faster
