ernie walks 1/6 mile in 1/12 hour when he walks along the river trail. How many miles per hour does Ernie walk when he hikes on

ohaa [14]

Answer:

2 miles

Step-by-step explanation:

distance=rate*time

d=rt

1/6=r*(1/12)

multiply both sides by 12

12(1/6)=r*(1/12)12

2=r*1

2=r

rate=2 miles per hour
