Record the speed of movement of the bee if it flies 7 m every second.
Formula for determining the speed of uniform motion
V = S / t;
V is the speed of the object;
S – distance traveled by the object;
t – time spent by the object on the way.
Travel speed can be expressed in km / h; m / s; m / min; km / s. The specific units depend on the magnitude of the object’s speed. The speed of the space station is 7 km / sec, and the walking speed of a person is 5 km / h. Time values are always whole values.
The values of the flight speed of a bee can be written in both m / s and km / h.
Let us substitute the values of the distance traveled and the time of movement of the bee into the formula for the speed.
Bee speed
V = S / t = 7 m / 1 sec = 7 m / sec.
Let’s translate into km / h.
1 km = 1000 meters;
1 hour = 3600 seconds.
1 meter = 0.001 km;
1 sec = 1/3600 hours;
V = 7 m / s = 7 * 0, 001 km * 3600 = 7 * 3, 6 = 25, 2 km / h.
When converting from m / s to km / h, use the coefficient 3, 6.
Answer: the speed of movement of the bee is 7 m / sec or 25.2 km / h.
