To determine how far a car travels in 15 minutes at a speed of 20 m/s, first convert the time from minutes to seconds, resulting in 900 seconds. The distance formula is used, where distance equals speed multiplied by time. By calculating 20 m/s multiplied by 900 seconds, the result is 18,000 meters, which converts to 18 kilometers. The discussion confirms the calculations and conversions are correct.

QUESTION: How far will a car travel in 15 min at 20 m/s?The answer was 18 km. but i don't know from where did they get this answer...can you explain it please step by step??

Thank you =)

Hint: Look at the units.

The car's speed is given in meters/second
The time is given in minutes
The answer is given in kilometers

So,we'll convert 15 min. to sec. = 900 s
meters into kilometers = 0.02 m
distance = 0.02 X 900 = 18 km.

Right??
 
You got it!

Thank You Brother thank you =))
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
