1: Each gallon of paint covers 200 square feet. I have to paint one side of a wall that is meters 12 tall and 60 meters long. If a foot is approximately 0.3048 meters, then what is the smallest whole number of gallons I can buy and have enough paint to cover the whole wall?

2:A cyclist travels at 20 kilometers per hour when cycling uphill, 24 kilometers per hour when cycling on flat ground, 30 and kilometers per hour when cycling downhill. On a sunny day, they cycle the hilly road from Aopslandia to Beast Island before turning around and cycling back to Aopslandia. What was their average speed during the entire round trip?

I cannot answer the second one since its the wrighting problem but for the first one its bassicly the same as the spray painting one. You just find out how many gallons needed and your done!

I don't quite see how you could answer #2, seeing as you have little context.

12 m x 60 m   x   1ft/.3048m  x 1ft/.3048 m  =  7750 ft2

7750 ft^2   /  200 ft^2/ gal   = 38.75 ~~~ 39 gallons of paint
