### Instruction: William runs at a constant speed of 8 miles per hour. Running at this constant speed, it takes William 75 seconds to run from his house to school. How many miles did William run?### Response: To find the distance William ran, I need to multiply his speed by the time he ran.
However, his speed is in miles per hour, and his time is in seconds, so I need to convert one of them to the same units.
I decide to convert his time to hours, since that is easier than converting his speed to miles per second.
To convert seconds to hours, I need to divide by 60 twice, since there are 60 seconds in a minute and 60 minutes in an hour.
So, 75 seconds is equal to 75 / 60 / 60 hours, which is 0.02083 hours.
Now, I can multiply his speed by his time to get his distance: 8 x 0.02083 = 0.1667 miles.
I round this to the nearest hundredth, since that is a reasonable level of precision for this problem.
