Question

In winter the temperature of a place fell at the rate of 2/5 degrees per day if the temperature is 20 degrees on the first day what would be on the fifth day

Answer 1

temperature falls at the rate of 2/5 = 0.4 ⁰ per day means that the temperature reduces by an amount of 0.4⁰ each day.

From 1st day to the 5th day, (during 4 days) the temperature falls by 4 * 0.4⁰.

so the temperature on the 5th day = 20⁰ - 4 * 0.4⁰ = 18.4⁰.

Answer 2

Answer:

it would be 18 degrees

Step-by-step explanation:

0.4 times 5=2

20-2=18
