How much longer does it take a automoblie to travel one mile at 20 miles per hour than at 30 miles per hour? show your work. a. 1 minute
b. 10 minutes
c. 20 minutes
d. none of these answers.

A

Step-by-step explanation:

At the rate of 20 miles per hour, the car will travel 20 miles every 60 minutes, or a third of a mile every minute. This means that it will travel a mile in 3 minutes. For the car travelling at 30 miles per hour, it will travel half a mile every minute, or a mile every 2 minutes. 3-2=1 minute, or choice A. Hope this helps!

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
