Answer:
B) -3 (Sorry if its overwhelming)
Explanation:
First, we have the given information of the weather over a 2 and 1/5 span
And we are asked to find the change per hour
We can first start by finding the change for 2 and 1/5 hours:
- Subtract the first amount by the second amount.
= (-6 3/5) - 0
= (-6 3/5) + 0
= -6 3/5
Now that we have the change for 2 and 1/5 hours we must find the change per hour:
- Divide the given dividend by the given divisor
= -6 3/5 ÷ 2 1/5
= -3
Hence, the temperature change per hour over a 2 1/5 hour span is -3° per hour
The temperature change per hour over a 2 1/5 hour span is -3° per hour.
The conversion formula for a temperature that is expressed on the Celsius (°C) scale to its Fahrenheit (°F) ;
°F = (9/5 × °C) + 32.
We can first start by finding the change for 2 and 1/5 hours:
Subtract the first amount by the second amount:
= (-6 3/5) - 0
= (-6 3/5) + 0
= -6 3/5
Divide the given dividend;
= -6 3/5 ÷ 2 1/5
= -3
Hence, the temperature change per hour over a 2 1/5 hour span is -3° per hour.
