If i walk 2 block in 15 minutes what will my speed be?

That means you walked 1 block in 7.5 minutes

Step-by-step explanation:

Divide 15/2 and that gives 7.5.

We can not find the speed unless if we are given the distance of the blocks but we can find the unit rate

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
