If you are using typical residential voltages ( 120v/240v) a 40 amp breaker is plenty big enough. You could even use a twenty amp breaker.
No you can't! If it's a 220 volt system. Then 220 * 40 = 8800 Watt maximum energy output.
Yes. watts / volts = amps. 4800/240=20amps.
Current in amps = watts/ voltage in volts. If you have a 240 volt supply, it will draw 4800/240 = 20 amps, so no. This is a very powerful water heater, and would normally be wired into a dedicated circuit, presumably with a 30 amp breaker.
Your term "hydro" is another term for kilowatt hours. So to answer your question a 4800 watt heater on for an hour would consume 4.8 kilowatt/hours. To take it further if you knew what you pay for a kilowatt hour in your area, multiply it by 4.8 and you could see how much it costs you to operate the heater. An example if you pay .11 cents a kilowatt hour, the price would be .528 or 53 cents an hour.
4800 metres = 2.9826 miles = 0.99419 of 3 miles So, to convert time for 4800 metres to time for 3 miles, divide the 4800 time by 0.99419 (or multiply by 1.00584)

Yes. watts / volts = amps. 4800/240=20amps.
4800 watts because watts = volts x amps.
Current in amps = watts/ voltage in volts. If you have a 240 volt supply, it will draw 4800/240 = 20 amps, so no. This is a very powerful water heater, and would normally be wired into a dedicated circuit, presumably with a 30 amp breaker.
5.5% of 4800= 5.5% * 4800= 0.055 * 4800= 264
4800
That is 4800
90% of 4800 = 4320= 90% * 4800= 90%/100% * 4800=43200/10= 4320
The value of 4800 is 4800 and probability has nothing to do with it.

30% of 4800 = 144030% of 4800= 30% * 4800= 0.30 * 4800= 1440
400 x 12 = 4,800
91% of 4,800 = 91% * 4800 = 0.91 * 4800 = 4,368
