Question 445323
So you want me to show you all of my work with the answer but you don't even share any of your work and the answer?
Jeremy walked faster and for more time
r=speed t= time d=distance
r*t=d
r and t are the speed and time for hugh
r+.5 and t+.5 are the speed and time for jeremy


(r+.5)*(t+.5)=10
r*t=7
solve for 
r and r+.5
t and t+.5
