To find out when Han and Tyler will meet, you can use the concept of relative speed. Since they're walking towards each other, their speeds will add up.
The total distance between them is 10 miles, and their combined speed is 12 mph (Han) + 15 mph (Tyler) = 27 mph.
To find the time taken to meet, you can use the formula: Time = Distance / Speed.
Time = 10 miles / 27 mph ≈ 0.37 hours.
Therefore, Han and Tyler will meet in approximately 0.37 hours or about 22 minutes.
