Answer:
It will take 7 hours for car B to catch up to Car A.
Step-by-step explanation:
So if you write the the two equations out:
![Car A=70x\\Car B= 90x-140](https://tex.z-dn.net/?f=Car%20A%3D70x%5C%5CCar%20B%3D%2090x-140)
You'll want to assume that x is how many hours and y is how many km.
The reason car B has, -140, is because car A is in front of it by two hours and in those two hours it reached 140km. Meaning that Car B is starting at 140 km behind Car A.
If you graph these two equations out you'll realize that they intersect at the point (7, 490). Meaning that Car B caught up with Car A after 7 hours and both cars had traveled 490km.

Answer:
Mauricio needs 10.5 liters of oil for frying.
Step-by-step explanation:
It is given that,
Mauricio can fry 6 potatoes using 1 liter of oil.
So, he can fry 18 potatoes using
= 3 liters of oil.
Thus, Mauricio fries 18 potatoes using 3 liters of oil per hour
Now, Mauricio wants to fry the 18 potatoes for 3.5 hours.
So, the total amount of oil needed by him = 3.5 × 3 = 10.5 liters.
Hence, Mauricio needs 10.5 liters of oil for frying.

The term would be genetic drift.
Genetic drift, also known as allelic drift, is one of the basic mechanisms of evolution, in which random changes in alleles from generation to generation in a population occur.
