Answer: 250 miles
Step-by-step explanation:
I am not sure what grade level you are, but this is how it is done in college.
I hope it can give you an idea and be of some help.
First you have to convert 150 minutes to hours. Then you multiply your new hours to 100 miles.
150 minutes x <u> 1 hour </u> x<u> 100 miles </u>= 250 miles
60 mins. 1 hour
Converting 200 miles to the amount of carbon dioxide emission that would be 1.884 tons annually. This will be the amount of carbon dioxide given that 200 miles is monthly covered.
