==========================================

Work Shown:

Method 1

Sam's unit rate is 12/2 = 6 km per hour.

Therefore he covers 6*4 = 24 km in 4 hours.

Recall that distance = rate*time.

--------

Method 2

(12 km)/(2 hrs) = (x km)/(4 hrs)

12/2 = x/4

12*4 = 2*x

48 = 2x

2x = 48

x = 48/2

x = 24
