on the first day of camp, Sara hiked 20 miles in 5 hours. At this rate how long would it take Sara to hike 12 miles?

3 hours

Step-by-step explanation:

20 ÷ 5 = 4 mph

12 ÷ 4 = 3 hours

hope this explanation makes sense! :)

9 hour

Step-by-step explanation:

sara hikes 20 mile in 5 hour

then, sara takes 5\20 hour to hike 1 mile

again if she hike 1 mile in 5\20 hour

then she to hike 12 mile she takes 5x12\20 = 9 hour

answer:     true

step-by-step explanation:

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!
