Answer:
B. l/Pr
Step-by-step explanation:
We are given that:
l = Prt
We want to get the value of the "t". This means that we want to isolate the t on one side of the equation.
To do so, we will need to get rid of the Pr. So, simply we will divide both sides of the equation by Pr as follows:
l = Prt
l/Pr = Prt / Pr
t = l/Pr
Hope this helps :)
