Answer: To compute the density of a spherical object, you must weigh it. Then you divide its mass by its volume to get its density. Keep in mind that an object's density has nothing to do with its size.
Step-by-step explanation:
1. σ is the density of the sphere.
2. M is the mass of the sphere.
3. r is the radius of the sphere.
She drives at a rate of 75 miles per hour for three hours, so the first thing you'd do is 75 x 3.
75 x 3= 225
So, she traveled 225 miles to the airport.
Then, she travels at a rate of 400 miles per hour for 4 hours.
4 x 400 = 1,600
That's 1600 miles she traveled from the airport to her destination.
Now to find the total number of miles traveled, add 1,600 and 225.
Total distance traveled: 1825 miles.
