Knowing the distance covered and the time to cover the distance,
you can calculate the car's average speed during that time.

Average speed = (30 km) / (20 minutes) = 1.5 km/minute .
Note: You do NOT have enough information to calculate velocity.

A scientific probe is a device that is sent to gather information from areas with harsh or dangerous conditions so as to not endanger humans. such devices may be sent to the sea floor, into a volcano, or into space. they collect information on those areas such as pressure, temperature, and makeup of the environment and send that information back to scientists so that they can evaluate and record that collected data.
