80 km
You do 240/60 which is 4 and then times that by 20. By dividing 240 by 60 you are finding how far it goes per minute and then you times that by how many minutes(20) which is 80 km
Answer:
(0.75) to the 3rd power is 0.421875
then multiply that by 240 and you get 101.25
rounded to the nearest 10th would be 101.3
Step-by-step explanation:
<u>We are given</u>
- Radius of Earth; 6.4 x 100 meters = 640 meters
Clearly, the shape of the earth is a sphere. Thus, to determine the volume of the earth, we will use a formula that determines the volume of a sphere.

When we substitute the radius in the formula, we get;


Take π as 3.14


Simplify the numerator;


Divide the numerator by 3;


-2 x 7 - 2 x 2n
(I think??)
