-------------------------
Old DATA:
rate = 22 mph ; time = 1/2 hr ; distance = rt = (1/2)22 = 11 miles
--------------------------------------
New DATA:
rate = x mph ; time = (25/60) hr. distance = rt = (25/60)x miles
--------------------------------------
Equation:
new distance = old distance
(25/60)x = 11
x = (60/25)11 = 26.4 mph (speed required to go 11 miles in 25 minutes)
