That was for the character limit thing!
Generally speaking mechanical energy is energy which physically moves (the object), while the thermal energy is energy from the movement of atoms.
Basically temperature is a measurement of atomic movement (doesn't move object as a whole).
Hence heat.
In order to find out the answer to this problem, you need to know how to find the unit rate. A unit rate a rate that has a denominator of 1. You find the unit rate because the problem is asking you to find the faster speed, but the ratios are different.
So 600m in 60 sec you divide both by 60. It comes out as 10m in 1 sec for the heron.
60m in 5 sec is 12m in 1 sec for the duck.
Compare the heron to duck. The heron travels faster.
Give 5 stars if it helped!! :)
