Working in minutes might give us a little more flexibility here, so we can start by converting 1 hour and 12 minutes, giving us 60 + 12 = 72 minutes for Chloe to drive 48 miles.

We can write her Chloe's rate then as 48 mi/72 min; since 48 and 72 have the factor 12 in common, we can reduce this to a rate of 4 mi/6 min. We want to find how many miles Chloe would travel in <em>60 minutes </em>at that rate. Since 60 = 6 x 10, we can scale the rate up by a factor of 10, getting us a rate of 4 x 10 = 40 mi/60 min, or 40 mph.

To find a speed in miles per hour, we need to divide a number of miles by a number of hours.

We are given 48 miles, so we already have a number of miles.

We are given the time as 1 hour and 12 minutes. We need to convert this time into hours.

1 hour + 12 minutes = 1 hour + 12/60 hour = 1.2 hours

speed = distance/time = 48 miles / 1.2 hours = 40 mph

Answer: The fourth choice, 40 mph.

Which ordered pair is a solution of the equation?<br> Y-4=7(x-6)
deff fn [24]

Answer:

(6,4)

Step-by-step explanation:

The equation is in 'point-slope' form.

y-y_1=m(x-x_1)\\\rule{150}{0.5}\\(x_1,y_1) \rightarrow \text{a point that's given}\\\\m \rightarrow \text{slope}

This means we can identify the point that was used in the equation.

y-\boxed{y_1} =m(x-\boxed{x_1}) | y-\boxed{4}=7(x-\boxed{6})\\\rule{210}{0.5}\\y_1 = 4\\\\x_1 =6\\\rule{210}{0.5}\\(x_1,y_1) \rightarrow \boxed{(6,4)}

(6,4) would be a solution to the equation given.

Hope this helps.
