suppose usual speed is x, then current speed is x/6.
to gain normal speed, he has to gain 5x/6
% increase = 100*(5x/6)/(x/6) = 500% - 13 years agoHelpfull: Yes(9) No(4)
- suppose usual speed is x, then current speed is x/6.
to gain normal speed, he has to gain 5x/6
if, x is 100%, then 5x/6 = ??
it will give 83.33 % - 13 years agoHelpfull: Yes(5) No(8)
- suppose usual speed is x, then current speed is x/6.
to reach normal speed, he has to gain by 5x/6.
% increase = 100*(5x/6)/(x/6) = 500% - 13 years agoHelpfull: Yes(3) No(0)
- %increase in speed= (change in speed)*100 / original speed
so
change in speed =x-(x/6)if x is the original speed
then,
%change=(5x/6)*100/x
ans=83.33% - 13 years agoHelpfull: Yes(1) No(6)
- jogger has to increase his speed by 20% (1/(6-1))
