Answer 1

Answer:

The average change in temperature over the last four days is 0.3°C

Step-by-step explanation:

We need to find the average daily change of temperature in the city over the 4 days. For this we find the change in temperature over the last 4 days and average it.

The temperature in the last 4 days are 1.34°C,-$\frac{5}{7}$°C, -0.75°C and $\frac{4}{9}$°C.

Change between first and second day = 1.34 + -$\frac{5}{7}$ = 2.05

Change between second and third day = -0.71 + 0.75 = 0.04

Change between third and fourth day = - 1.19

Average change = $\frac{2.05+0.04-1.19}{3}$ = 0.3°C
