Answer 1

Answer:

At the same rate Rose will run 3 miles in 42 minutes.

Step-by-step explanation:

Hint- This problem ca be solved using Unitary method.

This Here given that, Rose can run 4 miles in 56 minutes.

i.e Rose in 56 minutes can run 4 miles.

So Rose in 1 minutes can run $\dfrac{4}{56}$ miles.

So Rose in 42 minutes can run $\dfrac{4}{56}\times 42=3$ miles.

Therefore, if Rose can run 4 miles in 56 minutes, she will run 3 miles in 42 minutes.

Answer 2

$\frac{56}{42} = \frac{4}{x}$  then you figure out what you divide 56 by to get 4. which is 14. then you divide 42 by the same number 14.
