i cant do this with this given info lol

anonymous · Answer

@lgbasallote is right, the units that you copied here are wrong. Anyway, assuming both are speed, if person B has 5 min lead, she walked a distance 225 meters. We want to solve the time for which they were at the same position, so $$ s_{0} + v_b t = v_a t $$Which implies: $$225 + 45t = 50t $$Solve for t.

itz 45 right!

anonymous · Answer

225/5 is 45, indeed. But, please, take more care over your units. It's confusing both for you and for us.
