a. A bumblebee flies with a ground speed of 15.2 m/s. Calculate its speed in km/h.

Guida verificata passo dopo passo

Convert the speed from meters per second (m/s) to kilometers per hour (km/h) by using the conversion factor: 1 m/s = 3.6 km/h.

Multiply the given speed in m/s by the conversion factor to find the speed in km/h.

Set up the equation: speed in km/h = 15.2 m/s * 3.6 km/h per m/s.

Perform the multiplication to find the speed in km/h.

Ensure the units are correctly converted and the final answer is in km/h.

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Unit Conversion

Unit conversion is the process of converting a quantity expressed in one set of units to another. In this case, we need to convert the speed of the bumblebee from meters per second (m/s) to kilometers per hour (km/h). This involves using conversion factors, specifically knowing that 1 km equals 1000 meters and 1 hour equals 3600 seconds.

Conversion Factors

Speed

Speed is a measure of how fast an object is moving, defined as the distance traveled per unit of time. It is a scalar quantity, meaning it has magnitude but no direction. In this question, the speed of the bumblebee is given in m/s, which indicates how many meters it travels in one second.
