Ms. Handler drove at a rate of 75 km per hour. you do this by dividing the distance (225 km) by the time (3 hours) to get the average km traveled per hour
Product = multiply
(6x-y)*(2x-y+2) =
12x^2 -8xy + 12x + y^2 - 2y
For this case we can make the following rule of three:
9 1/2 m --------------> 28 1/2 rupees
26 1/3 m -------------> x
From here, we clear the value of x.
We have then:
Rewriting we have:
