For the first question, it's D. And the second question it's C.
Answer:
50 km/h
Explanation:
The average speed of the car is essentially the same thing as the unit rate.
Here a car goes 300 km for every 6 hours. To find the unit rate, we must find how many kilometers it goes per hour.
To do so, we can divide 300 by 6 to get a total of 50km/h.
The oxpeckers are two species of bird which make up the family Buphagidae. Some ornithologists regard them as a subfamily Buphaginae within the starling family, Sturnidae, but they appear to be quite distinct.Oxpeckers are endemic to the savanna of Sub-Saharan Africa. Both the English and scientific names arise from their habit of perching on large mammals (both wild and domesticated) such as cattle, zebras, impalas, hippopotamuses, or rhinoceroses, and eating ticks, small insects, botfly larvae, and other parasites.
According to the more recent studies of Muscicapoidea phylogeny the oxpeckers are an ancient line related to Mimidae (mockingbirds and thrashers) and starlings but not particularly close to either. Considering the known biogeography of these groups, the most plausible explanation seems that the oxpecker lineage originated in Eastern or Southeastern Asia like the other two.This would make the two species of Buphagus something like living fossils, and demonstrates that such remnants of past evolution can possess striking and unique autapomorphic adaptations.

The answer while be true because it's around the same rate.
