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

Let's break down the problem step by step:

1. You are initially driving at a speed of 1.5 miles per minute.

2. You slow down by 15 miles per hour. To convert miles per hour to miles per minute, we divide by 60 since there are 60 minutes in an hour. So, a reduction of 15 miles per hour is equivalent to a reduction of 15/60 = 0.25 miles per minute.

3. After slowing down, you reduce your speed by one third. To calculate this reduction, we multiply the current speed (1.5 miles per minute) by one third (1/3).

Now let's calculate the final speed:

Current speed: 1.5 miles per minute Reduction due to slowing down: 0.25 miles per minute Reduction by one third: 1.5 * (1/3) = 0.5 miles per minute

Therefore, after slowing down by 15 miles per hour and reducing the speed by one third, you are now traveling at a speed of 0.5 miles per minute.
