Question

Help with this problem please?
You're on a road trip with your family. You just passed a sign that tells you how many kilometers you have you drive before you reach your destination. You wonder how long it will take before you get there.
A formula describing this scenario is
r=d/t
where
d= distance to destination
r= rate of car (kilometers per hour)
t= time before you arrive

Rewrite the formula to determine how long it will take you to arrive.
