The common picnic ant walks with a velocity of 0.01 meters per second (m/s). How long will it take an ant to walk across a 8 ft long picnic table, assuming it does not meet with an untimely demise along the way?
(1 m = 39 in, 1 ft = 12 in)
8ft/1 X 12in/1in X 2.54cm/1in
0.01m/s x (39 in/m) x (1 ft/12 in) x #sec = 8 ft
Solve for # sec.
To find out how long it will take the ant to walk across the picnic table, we need to convert the length of the table from feet to meters and then divide it by the ant's velocity.
First, let's convert the length of the table from feet to meters:
8 ft * 12 in/ft * 2.54 cm/in * 1 m/100 cm = X meters
Multiplying the given values together, we get:
8 * 12 * 2.54 * 1 / 100 = X meters
This gives us the length of the picnic table in meters (X).
Now, we can calculate the time it will take the ant to walk that distance using the ant's velocity:
Time = Distance / Velocity
Time = X meters / 0.01 m/s
Now, substitute the value of X to solve for time:
Time = (8 * 12 * 2.54 * 1 / 100) / 0.01
Simplifying the equation:
Time = (8 * 12 * 2.54) / (100 * 0.01)
Time = 24.384 seconds
Therefore, it will take approximately 24.384 seconds for the ant to walk across an 8 ft long picnic table, assuming it can maintain a constant velocity and does not encounter any obstacles.
