Brian drives a distance of 250 m at a speed of 50 m/sec. With what speed should he drive so that he covers twice the distance in the same time?

100 m/s

Step-by-step explanation:

This can be done without a formula

If you think about it, as you walk faster you cover more distance (taking the same duration)

So if you double your velocity, you will double the distance you cover

Ps. Idk if this still helpful,

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
