 Unit Conversion Problem So in math class we are working on unit conversions. For part of our homework we had to create our own problem. I thought I should share it with you! I ran 82 miles in a week. How many hours per kilometer is this? So for this problem it is a two step because you have to change miles to feet and week to hours. So will first start off with changing miles to kilometers. This is how it looks like. Since we want miles to reduce we want to put miles on the bottom and km on the top. Since 1000m goes into 1km. This is how it looks like 82miles 1km -------× ------= 1 week 1000m Now you want to multiply them 82miles 1km 82 -------× ------= ----- 1 week 1000m 1000 Now that we have km taken care of we want to change weeks to hours. 82 km 1 week 1 day ----× -------×------- 1000w 7 days 24 hours Now weeks reduce and days reduce so we now multiply 82 km 1 week 1 day 82 km ----× -------×-------= --------- 1000w 7 days 24 hours 168000 hours We will now divide 82 and 168000 hours. This equals 0.000488 hours per kilometer. Article posted March 29, 2012 at 08:18 AM • comment • Reads 34 • see all articles |
