U=20m/c S=2км t=?

To solve for the time \( t \), we can use the formula for velocity, which is:

\[ v = \frac{s}{t} \]

where:

• \( v \) is the velocity,
• \( s \) is the distance,
• \( t \) is the time.

Given:

• \( U = 20 \, \text{m/c} \) (which is 20 meters per second),
• \( S = 2 \, \text{km} \) (which is equivalent to 2000 meters).

We can rearrange the formula to solve for \( t \):

\[ t = \frac{s}{v} \]

Substituting in the values:

\[ t = \frac{2000 \, \text{m}}{20 \, \text{m/s}} \]

Now calculating:

\[ t = 100 \, \text{s} \]

So, the time \( t \) is 100 seconds.
