Answer:
It takes 4.75 hours to travel 247 miles.
Step-by-step explanation:
This question is solved by proportions, using a rule of three.
A car travels at an average speed of 52 miles per hour.
This means that in 1 hour, the car travels 52 miles. How many hours for it to travel 247 miles?
1 h - 52 m
x h - 247 m
Applying cross multiplication



It takes 4.75 hours to travel 247 miles.
For ex:
U have 4/8 - 6/2 u would probably have to use KCF- Keep Change Flip
So then it’ll be 4/8 + 2/6
U kept the 4/8 then u changed the subtraction to addition and u flipped the 2 to the numerator and the 6 denominator.
Idk my dude this is what I can think of
