Write the expression as a unit rate. 124 meters in 8 seconds

To express the given quantity, 124 meters in 8 seconds, as a unit rate, we divide the distance by the time: \[ \text{Unit rate} = \frac{\text{Distance}}{\text{Time}} \] \[ \text{Unit rate} = \frac{124 \text{ meters}}{8 \text{ seconds}} \] \[ \text{Unit rate} = \frac{124}{8} \text{ meters per second} \] \[ \text{Unit rate} = 15.5 \text{ meters per second} \] So, the expression as a unit rate is \( 15.5 \) meters per second.
