Sita lives in Los Angeles, and her grandmother lives in Seattle. Sita plans to

visit her grandmother three times in the next year. What is the total distance
she will travel to make these three trips? Write and evaluate an expression that
uses multiplication to calculate the total distance traveled. Give your answer in
both decimal notation and scientific notation.
Los Angeles: 3.10801 x 10^3
Seattle: 3.50307 x 10^3

To calculate the total distance traveled, we need to find the sum of the distances for each trip.

Given that Sita plans to visit her grandmother three times, the expression to calculate the total distance traveled is:

3 * (3.10801 x 10^3 + 3.50307 x 10^3)

Simplifying this expression, we have:

3 * (6.61108 x 10^3)

Multiplying 3 by the sum of the two distances, we get:

19.83324 x 10^3

Converting this number to scientific notation, we get:

1.983324 x 10^4

Therefore, the total distance Sita will travel to make these three trips is approximately 19.83324 x 10^3 or 1.983324 x 10^4.
