Question

Select the correct answer. Martin runs 100 meters in 15 seconds. What is the equation for d, the distance in meters that Martin covers per second? A. 15 + d = 100 B. 100 + d = 15 C. d × 15 = 100 D. d × 100 = 15

Answer 1

To find the equation for d, the distance in meters that Martin covers per second, we need to use the formula:

distance = speed × time

Here, the distance covered by Martin is 100 meters, and the time taken is 15 seconds. Therefore, we can write:

distance = speed × time

100 meters = speed × 15 seconds

To find the speed, we can rearrange the equation as:

speed = distance / time

speed = 100 meters / 15 seconds

So the speed of Martin is:

speed = 6.67 meters per second

Therefore, the correct equation for d, the distance in meters that Martin covers per second, is:

d = speed

d = 6.67 meters per second

Answer: There is no option that matches the correct equation for d, which is simply d = 6.67 meters per second.
