Respuesta :

so 2.5 os to 50, aka 2.5:50
divide each side by 2.5 to get the answer.
if you dont have a calculator, divide each side by 5 to get .5:10, multiply by 2 to get 1:20
To solve this problem simply set up a fraction of a ratio with the 2 numbers.

Then make a new fraction and place the unknown as the variable, here it is x minutes

2.5 miles/50 minutes = 1 mile/ x minutes

X minutes = 50 / 2.5 = 20 minutes.

B is the correct solution.
