If a plane leaves and it takes two hours to get there. When it returns it takes 30 minutes longer because it was going 10mph slower. What was the speed
+36916 2 hr * x m/hr = 2 x miles
2 .5 hr * (x-10) = 2 x miles
2.5x - 25 = 2x
.5 x = 25
x = 50 50 miles hr going 40 coming back 100 miles (really slow plane)
