Long division.
Answer: 8 1/3 hours or 500 minutes
Step-by-step explanation:
Keep in mind that there are 100 centimeters in a meter.
The snail moves at a pace of 12 cm/h, and needs to go 100 cm. You can just divide 100/12 to get 8 1/3, which is how many hours (groups of 12 cm) it takes for the snail to travel 100 cm (1 meter).
If necessary, you can also multiply 8 1/3 by 60 to get the number of minutes the snail takes. 8 times 60 is 480, and 1/3 of an hour is 20, so add 480+20 to get 500 minutes.
As soon as you see "How many times . . .", that usually tells you that finding the answer involves <em>division</em>. (It certainly does in this one.)
(1.2 x 10⁵) / (4.9 x 10³) =
(1.2/4.9) x (10⁵⁻³) =
0.245 x 10² = <em>24.5 times</em>
It looks like <em>B</em> is the closest choice.
17 = p - 3 - 3p
Add 3 to 17.
20 = p - 3p
Combine p and 3p (addition)
20 = -2p
Divide by (-2p) to find p.
Since a negative divided by a negative equals a positive, -p would turn into a positive p.
-10 = p
