Mary rides her bike 45 1/2 miles in 1 5/8 hours if she rides at a constant rate how far will she ride in one hour

27.69 miles/hour

Step-by-step explanation:

Given that,

Distance covered by Mary = 45 1/2 = 45.5 miles

Time, t = 1.625  hour

We need to find how far will she ride in one hour.

Let it is x.

1.625  hour = 45.5 miles

1 hour  

So, she will ride at the rate of 27.69 miles/hour.

y + 11 = (1/4)(x + 16)

step-by-step explanation:

correct choice is b

step-by-step explanation:

when you calculate the average rate of change of a function, you are finding the slope of the secant line between the two points. for the function the average rate of change from point to point can be calculated as

to find the average rate of change from day 2 to day 10, note that at day 2, 8 houses were sold, so a(2,8) and at day 10, 2 houses were sold, so b(10,2). thus,
