Question

If you're driving one and a half miles per minute, slow down by 15 miles per hour, and then reduce your speed by one third, how fast are you going now

Answer 1

Answer:

We are moving at 50 mph

Step-by-step explanation:

Hello, great question. These types are questions are the beginning steps for learning more advanced Algebraic Equations.

The first thing we need to do in order to solve this problem is change the initial speed into mph.

$\frac{1.5mi}{1min} * 60min = \frac{90mi}{hour}$

Now we subtract the initial speed by 15 mph.

$\frac{90mi}{hour} - \frac{15mi}{hour} = \frac{75mi}{hour}$

Finally, we need to reduce the current speed by 1/3, this means that the final speed is 2/3 of the current speed. We can calculate this by multiplying the current speed by 2/3 like so,

$\frac{75mi}{hour} * \frac{2}{3} = \frac{50mi}{hour}$

Finally, we can see that we are moving at 50 mph

Answer 2

1.5 miles per minute is 90 mph.

Slowing down by 15 mph makes 75 mph.

Reduce speed by a third (25 mph) and that makes 50 mph.
