Answer:
Sheila travels 210 miles in 3 hours. At this rate how far will she travel in 7 hours?
Explanation:
- Calculating how many dogs Sheila has would be an addition problem.
- Calculating how much money Sheila will have paid in 7 months requires plugging 7 into the variable x for the equation 210+70x.
- Calculating how many more pens Sheila would need is a subtraction problem.
- Calculating how many Sheila will have traveled requires setting up a proportion in which (210)/(3)=(x)/(7). From there you would cross-multiply and then solve for x to get your answer.
