Question

Mr jones jogs the same route each day. the amount of time the jogs is inversely proportional to his jogging rate.

what option gives possible rates and times for two of his jogs?

Answer 1

If the relation is inversely proportiona means that

Running time = K / Jogging rate

Where K is a constant.

The you can write: Running time * Jogging rate = K

So multiply running time * jogging rate for each pair of data in the options; the option for which the products have the same value are the right answer.
