Question

The coordinate plane represents a map. Each grid unit represents 20 miles. A retail company has a warehouse at N(40, 60). A store is located at P(40, −30). How long will it take a truck driving at 50 miles per hour to drive from warehouse N to this store?

Answer 1

90*20= total distance between points
1800= 
1800/x=50/1
1800=50x
1800/50=x
36=x
it would take 36 hours
