Question

HELP + EXPLAIN PLEASE

Answer 1

Directly proportional would be the more weight the faster. But this relationship is inversely proportional which means the more weight the slower (less fast).

Answer 2

rate is inversely proportional to the weight
as one goes up the other goes down to keep a constant value, k
let the rate = r and the weight = w then rw = k
let the first rate and weight = r1 and w1 then r1w1 = k
let the 2nd rate and weight = r2 and w2 then r2w2 = k
k never changes and therefore r1w1 = r2w2
plug your numbers and solve to 2 decimal places then round to one decimal place to get your answer to the nearest tenth.

Answer 3

You can solve proportion problems with proportions, if you set them up properly, in this case:

\(\LARGE {s_0 \over s_1} = {m_1 \over m_0 }\)

Because this is an inverse proportion, the speed which goes with the first condition is on top, but the mass that goes with the first condition goes on the bottom.
