14mph

Explanation:

270 minutes = 4 hr and 1/2hr

63 miles = 63/4.5 = 14 miles per hour

Making the speed 14mph

Equation = h = 4.5     

(4h x 4h ) + (1 x 311/100) = 60

= 4h x 4h +( 1 x 311/100) =60

= 16h^2 + (1 x 311/100) =60

= 256h + (1 x 311/100) =60

= 256h + 14 = 60

= 270h  =  60

= h = 4.5
