On the graph

Question

Line 1 (0,0) and open dot on (2,4)
Line 2 (2,0) and closed dot on (5,9)
The graph represents precipitation over the last 5 hours in tenths of inches x-axis represents time in hours and y-axis represents precipitation in tenths of an inch. It rained the first 2 hours at a rate of 2 tenths of an inch per hour. It then began to snow and snowed at a rate of 3 tenths of an inch per hour How many tenths of an inch did it snow in total

Answer 1

To determine how much it snowed in total, we can analyze the information given about the precipitation over the last 5 hours.

1. Rain: For the first 2 hours (from time 0 to time 2), it rained at a rate of 2 tenths of an inch per hour.

   • Total rain = Rate × Time
   • Total rain = 2 tenths/hour × 2 hours = 4 tenths of an inch

2. Snow: After 2 hours, it began to snow, and it snowed from time 2 to time 5 (which is a total of 3 hours) at a rate of 3 tenths of an inch per hour.

   • Total snow = Rate × Time
   • Total snow = 3 tenths/hour × 3 hours = 9 tenths of an inch

Now, we can summarize:

• It rained for the first 2 hours: 4 tenths of an inch.
• It snowed for the next 3 hours: 9 tenths of an inch.

Thus, the total amount of snow is 9 tenths of an inch.
