Question 400375
1) At 45 mph, it takes 2.22...hours to travel 100 miles. Here's how you do this:
Divide 100 miles by 45 miles per hour.
{{{100/45 = 2.22}}}hours.
To convert this to minutes, multiply by 60 minutes per hour.
{{{(2.22)*(60) = highlight(133.33)}}}minutes.
2)If the density is 1.15gm/ml, then to find how many gms are needed to fill a  50 ml container, just multiply by 50.
{{{(1.15)(50) = highlight(57.5)}}}gm.
