Question

The temperature in Montreal, Canada went from 0° Celsius to 11.7° Celsius in a six hour period. If the temperature increased at a constant rate, how many degrees did the temperature rise per hour?

Answer 1

$Rate=\frac{\Delta temp}{\Delta time}$
$Rate=\frac{temp_{2}-temp_{1}}{time_{2}-time_{1}}$
$Rate=\frac{11.7\°-0\°}{6hr-0hr}$
$Rate=\frac{11.7\°}{6hr}$
$Rate=1.95\frac{\°}{hr}$
