Time and Distance: Comparing 85 km/h and 115 km/h Cars
Want To Learn More? To watch the entire video and ALL of the videos in the series:
In this video, we explore the concept of time and distance as we compare two cars traveling at different speeds along a straight highway. We'll calculate when the faster car arrives at a destination 16 km away and find out how far they must travel for it to arrive 15 minutes before the slower car. Join us for an engaging journey through the world of physics and velocity!
