Add 
to both sides:
Add the fractions in the left hand side:
So, the equation becomes

At 55 miles per hour, he travels 55 miles in every hour. So, in 2 hours he goes 55 x 2 miles, or 110 miles.
In the same way: at 70 miles per hour he goes 70 miles in every hour, and he only travels for an hour, so he goes 70 miles.
Going 50 mph (miles per hour) for 2 hours, he travels 50 x 2 miles or 100 miles.
Add these numbers up: 110+70+100 = 280.
Answer:
74%

Multiply both the numerator and denominator by 2 so that you will have a number over 100. After doing this you will have 74/100 which is 74%
To find the total snow fall you would multiply the amount of snow per hour by the number of hours it snows:
Total = 3/4 inch per hour x hours: Total = 3/4h
h = 12 hours:
Total = 3/4(12) = 9 inches total.
