Question

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?

Answer 1

$\large{\bold{\underline{Solution:}}}$

Degree of temperature dropped in last 30 days = 15°

∴ Degree of temperature dropped in last 30 days = $\bold{\frac{15}{30} = \frac{1}{2} \: degree}$

∴ Degree of temperature dropped in last 10 days = $\bold{\frac{1}{2} \times 10 = 5 \: degree}$

Thus, 5° temperature dropped in 10 days.

Answer 2

Answer:

5 degree Celsius.

Step-by-step explanation:

It is given in the problem that in the last 30 days the temperature dropped by 15 degree Celsius.

So, the rate of drop in temperature is 15/30=1/2 degree Celsius per day.

Now, as per the given condition, the rate of drop in temperature remains constant.

Therefore, in the next 10 days at this rate of drop, the temperature will drop by  (1/2)×10= 5 degree Celsius. (Answer)
