Atrain travels 67 kilometers in 1 hours, and then 81 kilometers in 5 hours. what is its average speed?

Average speed = (total distance) / (time to cover the distance)

Total distance = (67 km  +  81 km)  =  148 km

Time to cover the distance  =  (1 hr  +  5 hr)  =  6 hr

Average speed = (148 km) / (6 hr)  =  (24 and 2/3) km/hr

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
