the mass of ice taken = 10 g
the mass of water = 250 g
initial temperature of water = 20 C
the final temperature of water = 16. 8 C
specific heat of water = 4.18 J/g*K
the heat absorbed by ice to melt = heat loss by water
heat loss by water = mass X specific heat of water X change in temperature
heat loss by water = 250 X 4.18 X (20-16.8) = 3344 Joules
heat gained by ice = 3344 J
heat gained by ice = enthalpy of fusion X moles of ice
moles of ice = mass / molar mass = 10 / 18 = 0.56 moles
enthalpy of fusion = 3344 / 0.56 = 5971.43 J / mole

3420m
Explanation:
Given parameters:
Length of path = 6200m
time taken for the horse to run = 22.5min
speed = 152meters/minute
Unknown:
Distance run by the horse = ?
Solution:
Speed is the rate of change of distance with time.
Speed = 
Distance = speed x time
Distance = 152 x 22.5 = 3420m
