Answer:
The respective distances from Susan's grandparent's house and from Susan's school to miles are 75 miles and 6.25 miles.
What is the unitary method?
The unitary method approach is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.
Given:
Distance from Susan's grandparent's house = 120 kilometers
Distance from Susan's school = 10 kilometers
As given, 8 kilometers = 5 miles
Then, 1 kilometer = miles
So, we have to convert the distances i.e. 120 kilometers and 10 kilometers into miles.
120 kilometers = = 75 miles
10 kilometers = = 6.25 miles
