No, the water is identical, but because we know that c/5 = f-32/9, where c is Celsius and f is Fahrenheit, the thermometer scales differ. (This is how they are linked.)
The difference between Celsius and Fahrenheit is 1.8. In other words, 1 degree Fahrenheit is equivalent to 5/9 degree Celsius. Despite having rather significant variances, these two temperature scales collide at -40 degrees,
The Celsius scale, sometimes known as the centigrade scale, is a scale of temperature that is based on the freezing point of water at 0°C and the boiling point of water at 100°C. As a result, 100/5=212-32/9, which equals 20=180/9. The Fahrenheit temperaturescale is based on the fact that water freezes at 32°F and boils at 212°F.

There's not enough information in the question to calculate the player's velocity. But we can find his average speed.
Speed = (distance covered) / (time to cover the distance)
Speed = (15 meters) / (3 sec)
Speed = (15/3) (m/s)
Speed = 5 m/s
There's no information telling us what direction he ran, so it's not possible to say anything about his velocity. ('Velocity' is not just a big word for 'speed'. It's a different thing, and to describe it, you need to know the speed AND the direction of the motion.)
