Question 82 (ii)

Meterology one measure of average global temperature shows hwo each year varies from a base measure. The table shows results for several years.
$\begin{array}{cccccc}Year& 1958& 1964& 1965& 1978& 2002\\ Differencefrombase& {0.10}^{\circ }C& -{0.17}^{\circ }C& -{0.10}^{\circ }C& {\left(\frac{1}{50}\right)}^{\circ }C& {0.54}^{\circ }\end{array}$
See the table and answer the following:
In 1946 the average temperature varied by$-{0.03}^{\circ }C$ from the base measure. Between which two years should 1946 fall, when the years are ordered from coldest to warmest ?

Answer 1

In 1946, temerature is $-{0.03}^{\circ }C.$
We know that, $-{0.03}^{\circ }C$ lies between $-{0.10}^{\circ }C$ and ${\left(\frac{1}{50}\right)}^{\circ }C$ or ${0.02}^{\circ }C$
$\therefore -{0.10}^{\circ }C<-{0.03}^{\circ }C<{0.02}^{\circ }C$
Hence , he coldest to warmest order including 1946 is
1964 < 1965 < 1946 < 1978 < 1958 <2002
