For this problem the formula you need is below.
Rate Time = Distance
What you're asking is what the rate of the car was, so to do that, we must plug! (Rate will be represented by “x”)
First, we need to find out how many hours is 2 hours and 24 minutes. If there are 60 minutes in an hour, then we can just say 24 minutes is 24/60 or 2/5 hours. So 2 hours and 24 minutes equals 2.4 hours. Now we plug:
2.4x = 200
Then we divide both sides by 2.4:
2.4x/2.4 = 200/2.4
x = 83.33 kilometers per hour. is the answer
Hope this helps!
The surge protector doesn't use energy. The current that carries Energy may pass through it but a good surge protector won't consume any of that energy. It'll just pass through the surge protector. The current that carrys the energy passes through it to be used by devices further on down the line, such as a toaster or a welder. If those devices are using 1.8 kilowatts of power, then that means that 6,480,000 Joules of energy pass through the surge protector in one hour. They all come out the other end and keep going.
