Question

A weather forecaster predicts that the temperature will drop five degrees each hour for the next six hours. Represent this drop as a product of signed numbers and find the total drop in temperature.

Answer 1

We lose 5 degrees per hour so the temperature change is -5h where

h represents the number of hours

 

T_F = T_i - 5h

 

We are given that h = 6 hours so:

 

T_F = T_i - 30

 

T_F = Final temperature

T_i = Initial temperature

30^o is the total drop in temperature over the 6 hour period
