$3000 divided by 40 = 75...Mark as brainliest.......
X = 352.3 [your work is correct]
then the perimeter would be 352.3 + 352.3 + 280 + 280 = 1,264.55
The best way to do this is to set up a proportion
2 5
--- = ----
5 x
then cross multiply and divide
5 times 5=25/2=12.5
he would move 12.5 feet in 5 hours
