Question

Given the formula
solve for s.
A
s=btrs=\frac{bt}{r}s=
r
bt
​

B
s=brts=\frac{br}{t}s=
t
br
​

C
s=rtbs=\frac{rt}{b}s=
b
rt
​

D
s=brts=\frac{b}{rt}s=
rt
b

Answer 1

If the formula is b = r t s, isolate s by dividing both sides by r t:

s = b / (r t).

So the correct choice is D. (Requires r ≠ 0 and t ≠ 0.)
