If Jan takes exactly 30 minutes to walk to school each day, and her school is 2.3 miles away, what is her average walking speed (rounded to the nearest tenth)?
Geometry??
30/2.3 = 13.043 = 13.0 minutes per mile
To calculate Jan's average walking speed, you need to divide the distance she walks by the time it takes her.
In this case, Jan walks 2.3 miles to school and it takes her 30 minutes.
To find her average walking speed in miles per minute, divide the distance by the time:
Average walking speed = Distance / Time
= 2.3 miles / 30 minutes
To round the answer to the nearest tenth, divide the numerator (2.3) by the denominator (30) and round the result to one decimal place.
Using a calculator, divide 2.3 by 30, which equals 0.0766667.
Round the decimal to the nearest tenth, which is 0.1.
Therefore, Jan's average walking speed is approximately 0.1 miles per minute.
