If frank runs 55 feet on 10 seconds, at this rate how many feet will he run in 25 seconds

He can run 137.5 ft

Step-by-step explanation:

We can use a proportion to solve

55 ft               x ft

=

10 seconds        25 seconds

55 *25 = x*10

1375 = 10x

Divide each side by 10

1375/10 = 10x/10

137.5 = x

He can run 137.5 ft

the image of (6, 9) under a dilation is (4, 6). the scale factor is

c.
