Answer:
144
Step-by-step explanation:
Jane has 2 times as many books as Jill, so there are 3 parts. Two parts Jane and one part Jill. So, divide 216 by 3 and it's 72, which equals one part. Jane has two parts, so 72 x 2. Jane has 144 books.
Number 16- 216
number 17- 180
number 18- 252
We have to know divide the total meters that has been traveled by the tortoise which is for 4.8 meters to the time it was completed which is 3 minutes. The formula for speed is: [ speed = distance/time ]. So the equation will be 4.8 meters/3 minutes = 1.6 meters per minute. The speed of the tortoise is 1.6 meters per minute.
