Time needed = t = 20.83 s
<h3>Further explanation</h3>
Given
car speed = 85 km/h
truck speed = 73 km/h
Required
the time it takes for the car to reach the truck
Solution
When the car reaches the truck, the distance between them will be the same
x car - 250 m = x truck
General formula for distance (d) :
d = v.t
So the equation becomes :
85t-250 = 73t
12t=250
t = 20.83 s
Answer:
(C) increases; decreases
Explanation:
Since the two quantities are inversely proportional, it means that an increase in one quantity results in a decrease in the value of the other quantity. More so, an increase in the separation distance causes a decrease in the force of gravity and a decrease in the separation distance causes an increase in the force of gravity.

-- A tornado follows a path that's a few miles wide, for a few hours.
Then it's all over.
-- A hurricane follows a path that's several hundred miles wide,
for a week or two, before it's over.
Then comes the rain, continuing on the same path, for another week.
