Answer:
10 miles per hour
Step-by-step explanation:
there are 60 minutes in an hour once you covert you have that it took 1.17 hours then there are 5280 feet in a mile so you convert and get 12.075 miles
you divide
12.075/1.17 = 10.3205128
then you simplify to the nearest whole number and get 10
So first let me assume that the Total profit of the racquets are 8 percentage and not individually.
Now to find the profit we can do
20 x 100= 2000
Now
8=x/2000*100
X= 160
And now for loss
10x80=800
Now
15= x/800*100
X=120
Now profit =
160-120 = 40
The profit was only 40

Answer:
Roughly 18,000
Step-by-step explanation:
When you need to do rough mental math, you can do something like 720 vs 25 or 30 which is pretty simple to do in your head.
If you are very proficient in mental math, you can do something like 720 * 25, which is harder, but if you know the tricks, you can do this quickly.
720 * 25
Multiply 25 by 7.
175
Add two zeros.
17,500
Multiply 25 by 2
50
Add a zero.
500.
17500 + 500 = 18000
