please help, im in a really bad place rn and nobody ever helps. im about to fail the grade :( A train travels at a speed of 47mph and travels a distance of 323 miles. How long did it take the train to complete its journey

speed = distance ÷ time

we need time

time = distance ÷ speed

time = 323 ÷ 47

time = 6.8 hrs or 6hrs and 48 minutes

primary succession begins with a bare rock and ends with a forest secondary succession begins after a natural disaster where there is a temporary setback after a forest fire or local destruction, but the surrounding area can fill in

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.
