Answer:
2.4 miles
Step-by-step explanation:
Set the ratios:
[tex]\frac{3 miles}{25 minutes} = \frac{x miles }{20 minutes}[/tex]
Cross multiply:
3 * 20 = 25x
60 = 25x
Isolate the variable, x. Note the equal side, what you do to one side, you do to the other. Divide 25 from both sides:
(60)/25 = (25x)/25
x = 60/25
x = 2.4
2.4 miles is your answer.
