A thermometer has a range of 1.5 degrees of the temperature, what is the maximum and minimum at 87.4 degrees
Range = Max - Min
Divide this by 2 to get the lesser half and larger half:
Half-Range = 1.5/2
Half-Range = 0.75
Our Maximum temperature is:
Max Temp = Current Temp + Half-Range
Max Temp = 87.4 + 0.75
Max Temp = 88.15
Our Minimum temperature is:
Min Temp = Current Temp - Half-Range
Min Temp = 87.4 - 0.75
Min Temp = 86.65
Range = Max - Min
Divide this by 2 to get the lesser half and larger half:
Half-Range = 1.5/2
Half-Range = 0.75
Our Maximum temperature is:
Max Temp = Current Temp + Half-Range
Max Temp = 87.4 + 0.75
Max Temp = 88.15
Our Minimum temperature is:
Min Temp = Current Temp - Half-Range
Min Temp = 87.4 - 0.75
Min Temp = 86.65
