In one month, the low temperature
was 80 °f and the high
temperature was 18° f. find
the range in temperatures.

The range in temperature is 62° F

Step-by-step explanation:

The range is simply the difference between the highest and the lowest temperature recordings on that particular month.

We obtain the difference between 80 and 18;

80 - 18 = 62

The range in temperature is thus 62° F

c)462m

Step-by-step explanation:

If a person walks round the park, the person would be walking the whole perimeter of the trail

Perimeter = 2 x (length + breadth)

2 x (30m + 47m) = 154m

If he walks three times, the distance covered = 154m x 3 = 462m
