A town has accumulated 5 inches of snow, and the depth is increasing by 6
inches every hour. Another town has accumulated 9 inches of snow, and the depth is
increasing by 3 inches every hour.
How long until the snowfall in both cities is equal?

A. 1 hour and 20 minutes
B. 1 hour and 33 minutes
C. 45 minutes
D. 1 hour 15 minutes

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

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.

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.

she was supposed to add the hours(38.5) and multiply the amount of money she earned(7.50) resulting in $288.75 .

correct me if i'm wrong and if it is i'm truly sorry.
