an ostrich can run 6mph faster than a giraffe. An Ostrich can run 9 miles in the sime time that a giraffe can run at 8 miles per hour find the speed of each

Question

this is just a simpel word problem for college algebra

Answer 1

Let Vg is velocity of giraffe and Vo is velocity of ostrich. From the given information:

 

Vo = (Vg + 6) mph     (1)

 

From mechanics formula V = S/t  this means t = S/V, therefore, for equal time interval the ostrich and the giraffe:

 

t = So/Vo = Sg/Vg

9/Vo = 8/Vg          (2)

 

From (1) and (2)

 

Vo = 54 mph and

Vg = 48 mph
