Frank swims laps during swim practice. his coach tells him to swim a certain number of meters (total) each week. here's a formula for this scenario:

n=t/p

t= total number of meters
p= length of a lap (in meters)
n= number of laps frank swims

rewrite the formula to determine the length of a lap

N = t/p

t = total number of meters
p = length of a lap (in meters)
n = number of laps frank swims

Determine the length of a lap, p.

n = t/p

1) remove p as a denominator by multiplying both side w/ p.
p*n = p(t/p)
pn = t

2) remove n by dividing both sides with n.
pn / n = t/n

*numerator n and denominator n cancels each other out.

p = t/n
