A slope of 0.37   means that, for every 100 feet of horizontal change, the vertical rise = 37 feet

 

We can use a proportion here

 

 

.37 / 1   =  1 / x       cross-multiply

 

.37x  = 1*1

 

.37x  = 1       divide both sides by .37

 

x = about 2.702  units   [ with the 702 part repeating]  = 2.70  rounded
