Question

At 4 am, the temperature in Eastbourne was -5${}^{\circ }$C. By 1 pm, it had increased by 4${}^{\circ }$C. What was the temperature in Eastbourne at 1 pm?

• A. 4${}^{\circ }$C
• B. -1${}^{\circ }$C
• C. -5${}^{\circ }$C
• D. -9${}^{\circ }$C

Answer 1

The correct option is B

-1${}^{\circ }$C

Temperature at 4 am = -5${}^{\circ }$C

Rise in temperature = 4${}^{\circ }$C

Thus, temperature at 1 pm = -5${}^{\circ }$C + 4${}^{\circ }$C

= - ( 5${}^{\circ }$C - 4${}^{\circ }$) C
(since 5 > 4, the result of -5 + 4 will be negative)

= - 1${}^{\circ }$C
