<span>The actual time to travel would be 200 miles / 60 miles/hour = 3.33333 hours or 3 hours and 20 minutes. Since the van driver has been directed to allow an extra hour, the amount of time allowed should be 4 hours and 20 minutes for the total duration of the trip to Dallas.</span>
Answer:
V
Explanation:
The volt (symbol of the unit of volts, V ) is the SI - unit for electric potential and electric voltage (potential difference).
Answer:
35.7kJ
Explanation:
we can calculate the amount of heat energy required , using this formula
Q = mcθ
where.
Q = heat energy (Joules, J)
m = mass of a substance (kg)
c = specific heat capacity (units
)
θ = change in temperature (Celcius,C or Kelvin K)
Assume Specific heat capacity (c) of water =![4200Jkg^{-1} C^{-1}](https://tex.z-dn.net/?f=4200Jkg%5E%7B-1%7D%20C%5E%7B-1%7D)
mass =0.1 kg
![Q=0.1 kg*4200Jkg^{-1} C^{-1}*85C\\=35700J\\=35.7kJ](https://tex.z-dn.net/?f=Q%3D0.1%20kg%2A4200Jkg%5E%7B-1%7D%20C%5E%7B-1%7D%2A85C%5C%5C%3D35700J%5C%5C%3D35.7kJ)
540 meters should be the answer

Answer:
Turning off your lights will also help reduce the use of non-renewable resources that are harmful to the environment. You can turn off the lights during the day especially if you don't need them. You can also turn off your appliances to help reduce your carbon footprint and help save the planet.
