y=

Answer:
kilometers per hour.
Step-by-step explanation:
We have been given an
, which describes the number of kilometers y that a van travels in x minutes. We are asked to to find the constant speed of the van in terms of hours.
We can see that van travel
kilometers in x hours. To find the constant speed of van, we will substitute
in our given equation as:


Since van travels
kilometers in one hour, therefore, constant speed of van is
kilometer per hour or
kilometers per hour.
I am not sure...but....
(780/1950) * 360 ( as a circle has 360 degrees, you multiply with 360)
Ans= C 144.
