Answer:
Speed
Explanation:
Aliyah must have been trying to find her speed.
The speed is a measure of how fast an object or a body is and it is calculated by finding the ratio of distance with time. Mathematically,
speed = 
with a unit of m/s.
<em>Hence, with the distance measured on the ground and Aliyah trying to find the time it will take her to cover the distance while running, she must have been trying to find how fast she can run, that is, speed. </em>
Coronavirus??? I guessed sorry :/
Answer: The boiling points of the two liquids are quickly exceeded
Explanation:
Fractional distillation is a method of separating a mixture of liquids where each has different boiling points.
To therefore obtain individual fractions, temperature rise of the mixture must be gradual, otherwise the boiling points of the two liquids will be quickly exceeded making collection of each fraction impossible.
