Sienna can walk 3 miles in 45 minutes. If she keep the same pace how many miles can she walk in 2 hours

2 hours = 120 minutes

Set up a proportion.

3/45 = x/120

Cross multiply

3*120 = 360

45*x = 45x

45x = 360

45x/45 = 360/45

x = 360/45

x = 8

Final answer: She walks 8 miles in 2 hours.

45 Minutes is 3/4 hour. I dont really know how to explain the rest, but rhe answer is 8 miles.
