Can You Outsmart Einstein in this Easy Question?

[00:00:00]You will fall for this intuition question, just like Einstein almost did.

[00:00:03]And it's quite simple. Imagine you're driving a car at 60 km/h from point A to point B. At what speed do you need to travel back to point A such that your average speed for the entire two-way journey is 120 km/h. Pause to think about it. It's not 180 km/h. The formula is speed equals distance over time. For the first journey, we traveled a distance of X at 60 km/h. So, let's sub all these values into the formula. And let's say the time is T1. For the full two-way journey, you travel 2X at 120 km/h. And let's say time is T2. But, we can divide by two on both sides, leaving us with 60 equals X over T2, which is identical to the first journey, meaning that T1 and T2 should be exactly the same. What this means is that the time taken to go from point A to point B is the same as the entire two-way journey.

[00:00:50]In other words, you would need to instantly go from point B to A to make the average velocity 120 km/h. And that's why that
