The temperature dropped 15 degree Celsius in the last 30 days. If the rate of temperature drop remains the same, how many degrees will the temperature drop in the next ten days?

Degree of temperature dropped in last 30 days = 15 degrees
Degree of temperature dropped in last 1 day = 15/30 = 1/2 degrees
Degree of temperature dropped in last 10 days = 1/2×10 = 5 degree
Thus, 5 degree Celsius temperature dropped in 10 days.
