Explanation:

It is given that the energy produced by a person’s body due to metabolism is at a rate of 500W.

Energy produced by him in 1 hour

= 1800000 J

Of this, 80 % is converted into heat.

Heat energy produced

= 1440000 J =1.4x10^6

1.44x10^6/2.42x10^6=0.595kg

One of the many random useless factoids that I carry around
in my head is the factoid that 60 miles per hour is equivalent
to exactly 88 feet per second.

So in three seconds at that speed, you would cover exactly

                       (3 x 88) = 264 feet.
