Step-by-step explanation:
3000 W = 3 kW
3 kW(4hr/day)(30 day/month) = 360 kWh/month
360 kWh/month($0.15 / kWh) = $54

Answer:
Step-by-step explanation:
- Start time = 2 PM
- Speed of the first train = 50 mph
- Speed of the second train = 60 mph
- Trains head same direction
- The second train spends 3 hour less time than the first but both take same distance
<u>Let the time in travel for the first train be x, then we have equation for distance:</u>
- 50x = 60(x - 3)
- 50x = 60x - 180
- 60x - 50x = 180
- 10x = 180
- x = 18 hours
<u>Time when the second train caches up the first one:</u>
- 2 PM + 18 hours = 8 AM next day
