Answer:
2 hours
Step-by-step explanation:
The initial difference in depth is 10-4 = 6 inches. The difference in snowfall rates is 6-3 = 3 inches per hour.
At that rate, the difference in depth will be made up in ...
(6 in)/(3 in/h) = 2 h
In 2 hours the snowfall in the two towns will be equal.
_____
You could write equations for depth, then equate them.
d1 = 4 +6h
d2 = 10 +3h
d1 = d2 . . . . . . . . . . for some value of h the depths will be equal
4 +6h = 10 +3h
h(6 -3) = 10 -4 . . . . . subtract 3h+4 from both sides
h = 6/3 = 2
Snowfall will be equal in 2 hours.
