We are told in the question that 1 carat is equal to 200 mg.
The Hope Diamond is 44.5 carats. Let's multiply the weight of 1 carat by 44.5 to get the weight of the Hope Diamond in mg:

The total weight of the Hope Diamond is 8,900 mg. However the question asks for the weight in grams. There are 1000 mg in 1 gram, so let's divide the known weight of the Hope Diamond in mg by 1000 to get the weight converted to grams:

Now we know that
the weight of the Hope Diamond is equal to 8.9 grams.
Answer:
2222
Step-by-step explanation:
2222
To solve for this we will be using the formula S = D/T
S = Speed
D = Distance
T = Time
First we need to re-arrange this formula to solve for time
T= D/S
T = 400/230
T=1.74 hours
.74 hours is close enough to .75 that we can say it is 45 minutes
So it is 1 hour and 45 minutes
The area is 4 square meters, because 2x2 would be 4
