Plz me someone! carol and nora left the library at the same time. carol biked east at a speed of 8 miles per hour. nora biked west at a speed of 10 miles per hour. how far apart were carol and nora after 3 hours?

I'm not sure if my answer is right, but I think after 3 hours they would be 54 miles apart. Because if Carol goes east 8 mph that means she has gone 24 miles in 3 hours because 3 x 8 = 24. And if Nora went 10 mph going west then she has gone 30 miles because 10 x 3 = 30. Then you do 30+24 and get 54. I hope that makes sense :)

Well if Carol goes 8 mph then you do 8 x 3 = 24     And Nora is going 10  then you do 10 x 3 = 30  ...30 + 24 = 54 miles apart in 3 hours
