Answer:
Step-by-step explanation:
(168 mi)/(7 hr) = (24 mi)/hr
(2.5 hr) × (24 mi)/hr = 60 mi
If an object has a density of less than g/ml, the object will float in water.
So, fourth option is correct
The object with density less than g/ml will float, and the object with a density more than g/ml will sink.
So, if an object has a density of less than g/ml, the object will float in water.
Therefore, fourth option is correct

Answer: d
<u>Step-by-step explanation:</u>
Using the volume formula, we will see that the volume of the sphere is V = 381.51 cm^3
<h3>
How to get the volume of the sphere?</h3>
For a sphere of radius R, the volume is given by the formula:
In this case, we can see that the diameter is 9 cm, then the radius is half of that:
R = 9cm/2 = 4.5cm
Now that we know the radius, we can replace it on the volume formula to get:
