Answer:
100/3 meters per min
Step-by-step explanation:
Im kinda unsure about this one.
It took 3 minutes for John to travel 200m and Sam to travel 300m.
You have time and distance so you can use that to find velocity.
John: 200/3 m/min
Sam: 300/3 m/min
take the difference between the two to get your answer.
|200/3 - 300/3| = 100/3 m/min
It would be 5 because its closer to five then it is 4
There are technically still 6 subs, but there are 30 bits or smaller sandwiches
Since all the volume of the liquid will be contained by all 30 spheres then,
30 V = 3392.92
where V is the volume of each sphere
Solving for V
V = 113.0973
The formula for the volume of the sphere is:
V = (4/3) π r³
Since diameter, D = 2r
V = (4/3) π (D/2)³
V = (4/3) π (1/8) D³
V = (1/6) π D³
Since V = 113.0937
113.0937 = (1/6) π D³
D = 6
Therefore, the diameter is 6 inches (THE THIRD OPTION)
