About how many inches did the level rise?

Question

During a storm the level of ariver rose 10 1/2 inches in 4 1/2 hours.

Answer 1

Sally,

Is the question asking how much did the level rise in 1 hr

 

In 1 hr it rose 10.5/4.5 = 2 1/3 inches or 2.33 inches

 

If the question is asking for a different amount of time say 2 hrs, multiply the above answer by 2.
