Answer:

31.67 mph

Explanation:

To calculate the average speed of the truck, we must first obtain the total distance travelled by the truck followed by the total time taken for the truck to cover the distance travelled.

The following data were obtained from the question include:

Total distance) = 30 + 45 + 50 + 65 = 190 miles

Total time = 1 + 2 +1 +2 = 6 hours

Average speed =.?

Average speed = Total distance / Total time

Average speed = 190 /6

Average speed = 31.67 mph

Therefore, the average speed of the truck is 31.67 mph

Magnesium combined with chlorine.

How?

Look at the question .Compound has -1 charge in it .Hence it contains Halogen.
Looking at the options Option B and C contain Iodine and chlorine i.e halogens .

Now come to metals side.

Potassium has valency 1(Look the Electronic configuration below)

$\\ \sf\longmapsto 1s^22s^22p^63s^23p^64s^1$

Hence it will contain +1 charge which is omitted directly .

Now come to option C.

Magnesium has charge +2(Look at EC below

$\\ \sf\longmapsto 1s^22s^22p^63s^2$

Hence the compound formed is given by

$\\ \sf\longmapsto MgCl_2$

Hence option C is correct.
