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.

4

step-by-step explanation:

6 (donuts) divided by 3 is 2.

so 2/3 means 2 times 2, which is 4/6.

you get two and your friend gets four.

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
