Short answer A
This one is exactly the same (with number changes) as the last one. You cannot use t which is in time, to mix with pure numbers which in this case is grams. That means that both C and D are incorrect.

Now as with the last one, are you going to raise e to a minus number or a plus number? Remember that if e is raised to a plus number, the sample in this case will increase. You are watching a radioactive decay. The number has to be smaller. So B is eliminated. There is only one answer left and that's A. It should be correct.

We have:

v = \frac{d}{t}

t * v = d

Make t the subject

t =\frac{d}{v}

v = \frac{d}{t}

Cross multiply

d = v * t

d = vt
