In A speed boat moving at a velocity of 25 ms runs out of gas and drifts to a stop 3 minutes later 100 meters away. What is its rate of deceleration?

To find the rate of deceleration, we need to first convert the time to seconds. 3 minutes is 180 seconds. Then, we can use the formula for acceleration: acceleration = change in velocity / time taken. The change in velocity is from 25 m/s to 0 m/s, which is -25 m/s (negative because it's decelerating). So, the rate of deceleration is -25 m/s / 180 s = -0.139 m/s².
