Question

Arianna spends a winter day recording the temperature once every three hours for

science class. At 9 am, the temperature was -6.7°F. Between 9am and noon, the
temperature rose 10.7°F. Between noon and 3pm, the temperature went up 14.8°F.
Between 3pm and 6pm, the temperature decreased by 12.9°F. What was the
temperature at 6pm?

Answer 1

6°F

Explanation:

at 9am temperature= -6.7° F

between 9am and noon temperature rose 10.7°F

therefore temperature at noon the temperature= -6.7° + 10.7°= 4°F

between noon and 3pm temperature went up 14.8°F

therefore temperature at 3pm=4+14.8=18.8°F

between 3pm and 6pm the temperature decreased by 12.8°F

therefore the temperature at 6pm= 18.8-12.8= 6°F

the temperature at 6pm Iis 6° F
