Anthony and Adam were running in a race.anthony finished the race in 6.3 minutes.adam finished the race in 4.92 minutes. How much faster was Adam than Anthony ?
+33616 speed = distance/time
Adam's speed = L/4.92 if L is the distance.
Anthony's speed = L/6.3
Adam's speed/Anthony's speed = (L/4.92)/(L/6.3) = (L/4.92)*(6.3/L) = 6.3/4.92
$${\frac{{\mathtt{6.3}}}{{\mathtt{4.92}}}} = {\frac{{\mathtt{105}}}{{\mathtt{82}}}} = {\mathtt{1.280\: \!487\: \!804\: \!878\: \!048\: \!8}}$$
so Adam is approximately 1.28 times as fast as Anthony, or about 28% faster.
