(02.03 MC) The temperature at a mountain base camp was −2 degrees Celsius on Thursday. Friday morning, the temperature was 1 deg

aev [14]

Answer:

The temperature at the base camp Friday evening is - 6 degrees Celsius.

Step-by-step explanation:

To get the temperature at a mountain base camp on Friday evening, we must translate statement into a mathematical form:

(i) The temperature at a moutain base camp was - 2 degress Celsius on Thursday:

$T_{o} = -2\,^{\circ}C$

(ii) Friday morning, the temperature was 1 degree Celsius lower than it was on Thursday:

$\Delta T_{1} = -1\,^{\circ}C$

(iii) Friday evening, the temperature was 3 degrees Celsius lower that it was that morning:

$\Delta T_{2} = -3\,^{\circ}C$

The temperature at the base camp Friday evening is:

$T = T_{o}+\Delta T_{1}+\Delta T_{2}$

$T = -2\,^{\circ}C-1\,^{\circ}C-3\,^{\circ}C$

$T = -6\,^{\circ}C$

The temperature at the base camp Friday evening is - 6 degrees Celsius.
