Answer:
There's not enough information to answer this. You need to provide the information on the people.
With the given information we can calculate instatenous speed and average speed
To calculate instantaneous speed, we need to divide part of the total distance traveled by time. However, we don't want to use the distance of the entire trip, because that will give us average speed.
Average speed = Distance / time
Velocity = displacement/time
Displacement. = v × t
Plants use carbon dioxide and sunlight to make their own food and grow. The carbon becomes part of the plant. Plants that die and are buried may turn into fossil fuels made of carbon like coal and oil over millions of years. When humans burn fossil fuels, most of the carbon quickly enters the atmosphere as carbon dioxide.
i hope this helps ^^
