Question 1030616
let the returning speed be x mph
going to game speed = x+24

Distance = 48
 1 hour more while returning

time return - time going = 1

48/x - 48/(x+24)=1

LCD=	x	(	x	+	24	)												
multiply by LCD																		
48	(	x	+	24	)	-	48	x	=	1	x	(	x	+	24	)		
48	x	+	1152	-	48	x	=	1	X^2	+	24	x						
1152	=	1	X^2	-	24	x												
	X^2		+	24	x		-1152	=	0									
x^2 +48x-24x-1152=0

x(x+48)-24(x+48)=0

(x-24)(x+48)=0

x=-48 OR 24

x =24
24 km/h while returning

while going speed = 24+24 = 48 km/h
