Answer:
Therefore,
Distance of the trip is
Step-by-step explanation:
Let "x" be the Speed of the car and,
"y" be the time to cover the trip to her grandparents,
To Find:
How long is the trip = ?
Solution:
We Know that,
According to the First given condition,
According to the Second given condition,
As we know Distance will remain same so we have
Substituting the values we get
So on Substituting we have
..............Equation ( 1)
Again on Substituting we have
...........Equation ( 2)
Subtracting Equation 1 from equation 2 we get
Substitute y = 12 in equation 1 we get
So we have now,
Therefore the Distance of the trip is
Therefore,
Distance of the trip is
