The world speed record on water was set on October 8, 1978 by Ken Warby of Blowering Dam, Australia. If Ken drove his motorboat a distance of 1000. m in 7.045 s, how fast was his boat moving in m/s?
To calculate the speed of Ken Warby's motorboat, we can use the formula:
Speed = Distance / Time
Given:
Distance = 1000 m
Time = 7.045 s
Substituting these values into the formula:
Speed = 1000 m / 7.045 s
Calculating the values:
Speed = 142.05 m/s
Therefore, Ken Warby's boat was moving at a speed of approximately 142.05 m/s.
To find the speed of Ken's boat, we need to divide the distance traveled by the time taken.
The given distance is 1000 m and the time taken is 7.045 s.
To calculate the speed, we use the formula:
Speed = Distance / Time
Plugging in the given values, we have:
Speed = 1000 m / 7.045 s
Calculating this, we get:
Speed ≈ 141.86 m/s
Therefore, Ken's boat was moving at a speed of approximately 141.86 m/s.
distance = speed * time
so plug in your numbers
