What is the median of this data set?

Answer:

Therefore, after 1 hour and 20 minutes, the snowfall in both cities was equal to 13 inch.

Step-by-step explanation:

Calculating the depth of First Town:

First town has accumulated 5 inches of snow.

As the depth is increasing by 6  inches every hour

• i.e. 6 inch  = 1 hour

so the depth increase after 45 minutes i.e. 3/4 hour  =  4.5 inch

so

After 45 minutes

Snow level of First town after 45 min = 4.5 + 5 = 9.5 inch

After 1 hour

Snow level of First town after 1 hour = 5 + 6 = 11 inch

After 1 hour and  20 minutes

5 + 6 + 2 = 13 inch     ∵ If 6 inch per hour, then 2 inch in 20 min

Calculating the depth of Second Town:

Second town has accumulated 9 inches of snow.

As the depth is  increasing by 3 inches every hour.

• i.e. 3 inch  = 1 hour

so the depth increase after 45 minutes i.e. 3/4 hour  = 2.25 inch

so

After 45 minutes

Snow level of Second town after 45 min = 9 + 2.25 = 11.25 inch

After 1 hour

Snow level of Second town after 1 hour = 9 + 3 = 12 inch

After 1 hour and  20 minutes

Snow level of Second town after 1 hour and 20 minutes

9 + 3 + 1 = 13 inch   ∵ If 3 inch per hour, then 1 inch in 20 min  

From the above observation, it is clear that after 1 hour and 20 minutes the snowfall in both cities was equal.

Therefore, after 1 hour and 20 minutes, the snowfall in both cities was equal to 13 inch.
