Hmm this ones tricky.....
Answer:
Han's younger sister accelerated at a rate of 0.5 meters per square second during that time.
Step-by-step explanation:
Let suppose that Han's younger sister accelerates at constant rate, then, acceleration (
), measured in meters per square second, can be calculated by the following equation:

Where:
,
- Initial and final times, measured in seconds.
,
- Initial and final speeds, measured in meters per second.
If we know that
,
,
and
, the acceleration of the younger sister is:


Han's younger sister accelerated at a rate of 0.5 meters per square second during that time.
Answer:
1.8 km
Step-by-step explanation:
The scale on the map is 1 : 15000.
This means that every 1 cm on the map is equal to 15000 cm on the ground.
12 cm on the map will therefore be:
12 * 15000 = 180000 cm
Let us convert to kilometres:
100000 cm = 1 km
180000 cm = 180000 / 100000 = 1.8 km
12 cm on the map will be 1.8 km on the ground.
Answer:
The answer is 600
Step-by-step explanation:
Because 50×12=600
