Answer:

42.0×10² second²

Explanation:

Here, time is given in milisecond

(64800 ms)²

= 4199040000 ms²

The SI unit is seconds

1 second = 1000 milisecond

$1\ milisecond=\frac{1}{1000}\ second$

$\\\Rightarrow 1\ milisecond^2=\left(\frac{1}{1000}\right)^2\ second^2$

$4199040000\ ms^2=4199040000\times \left(\frac{1}{1000}\right)^2\ second^2=4199.04\ second^2$

City A will have a higher temperature overall than City B (D)

Explanation:

If all factors other than elevation are the same for both cities, then City A will have a higher temperature overall than City B. This is because there are fewer air molecules at higher elevations. Fewer air molecules mean less heat is absorbed by the atmosphere, and temperatures are lower. This is why areas high in the mountains are often much cooler than areas down on the plains.
