Answer: 53.659 seconds
Step-by-step explanation:
Given: Vega swam her leg of the race in 27.98 seconds.
Janice swam her leg of the relay race in 25.679 seconds.
Then , their combined time for their part of the relay = (Time taken by Vega) + (Time taken by Janice)
= 27.98 seconds +25.679 seconds
= (27.98+25.679) seconds
= 53.659 seconds
Hence, their combined time for their part of the relay = 53.659 seconds

Answer: Choice A) 252 in^2</h3>
=======================================================
Explanation:
Refer to the diagram below.
The red rectangle is 6 inches by 12 inches, so its area is 6*12 = 72 square inches. There are two of these rectangles (one on top, one on the bottom). That accounts for 2*72 = 144 square inches so far.
The purple rectangles are 3 inches by 12 inches, yielding an area of 3*12 = 36 square inches each. That's another 2*36 = 72 square inches when we account for the front and back purple rectangles.
The green rectangles are 6 inches by 3 inches. Each green rectangle is 6*3 = 18 square inches. Having two of them means we'll add on 2*18 = 36 square inches.
Overall, the entire surface area is the sum of all the areas we calculated: 144+72+36 = 252 square inches, which is choice A
-------------------------
Alternative Method:
- L = 12 = length
- W = 6 = width
- H = 3 = height
SA = surface area of the rectangular prism
SA = 2*(L*W + L*H + W*H)
SA = 2*(12*6 + 12*3 + 6*3)
SA = 2*(72 + 36 + 18)
SA = 2*(126)
SA = 252 in^2
So we get the same answer either way
