A backpacking club can average 2 miles per hour. At that rate, how long will it take for a hike of 8 miles?

It takes 3.5 hours to do the hike.

Step-by-step explanation:

since the average rate = the total distance / the total time or

v = d/t, where v = the rate, d= distance, t = time

t = d/v

v = 2 1/2 miles per hour = 2.5 miles per hour

d = 8 3/4 miles = 8.75 miles

t = 8.75/2.5

t = 3.5 hours

it takes 3.5 hours to do the hike.

d

step-by-step explanation:

given

y + 3 = - 4(x - 2) ← distribute the parenthesis

y + 3 = - 4x + 8 ( subtract 3 from both sides )

y = - 4x + 5 → d
