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.
