Two persons are to run a race, but one can run 10 meters per second, whereas the other can run 4 meters per second. if the slower runner has a 75-meter head start, how long will it be before the faster runner catches the slower runner, if they begin at the same time?

12.5 seconds

Step-by-step explanation:

Speed of the first person = 10 meter per second

Speed of the second person = 4 meter per second

Relative velocity of faster person = 10 - 4 = 6 meter per second

since distance between both the person is = 75 meter.

Therefore, time to cover this distance by faster person =

= 12.5 seconds.

Faster runner catches the slower runner after 12.5 seconds.

company a

step-by-step explanation:

using the linear regression models , it is found that company a   pays about $14 more. but using the same regression (linear) company b pays about $10 more.

so company a pays more than b
