Help Please, Is this right? Homework?

Are these work/answers right? How do I C?

1. A person running at the pace of 5mph expends 300 kilocalories of energy per hour.

a)Find the power of the runner is exerting while running.

b)Find the total energy exerted by the runner in a 10k run

1a) power = energy / time

= 300000J/ 3600s

=83.3333 j/s

b) 5m/h = 0.0013889 m/s

speed = dist /time

0.0013889 = 10000 / t

t = 719994.24s

83.3333 = energy / 719994.24

energy = 59999496

= 6000kc
