Question

If a woman runs at a speed of 7(m)/(s) for 30s, how far does she run?

a. 210m
b. 0.033m
c. 4.28m
d. 30m

Answer 1

The woman covers a distance of 210 meters in 30 seconds.

Step-by-step explanation:

In order to determine the distance covered, we can use the formula:

`\[ \text{Distance} = \text{Speed} * \text{Time} \]`

Given that the speed is
`\(7 (m)/(s)\)` and the time is 30s, we can substitute these values into the formula:

`\[ \text{Distance} = 7 (m)/(s) * 30s = 210m \]`

So, the woman runs a total distance of 210 meters in 30 seconds. This calculation is derived from the basic kinematic equation that relates speed, time, and distance.

In summary, the woman's speed of
`\(7 (m)/(s)\)` maintained for 30 seconds results in a distance covered of 210 meters. This implies that for each second, she covers 7 meters, and over the course of 30 seconds, the cumulative distance is 210 meters. The straightforward application of the speed-time-distance formula allows us to arrive at this conclusion.
