Answer:
B
Explanation:
The formula for distance is rate × time.
Flow and work don't make sense. Also, work is force × distance.
However, you were given rate is equal to distance/time (r=d/t) and were asked to find what distance would be:
in that case, we'll isolate d onto one side
here's the equation
r=d/t
multiply by t on both sides
rt=d, or rate × time equals distance
either way it's B
