John jogged downhill at 6mi/hr and then jogged back up at at 4mi/hr. If the total jogging time was 1.25 hours, how far did he jog in all?
i would think
first find the average of her running speed
= 4 m/hr + 6 m/hr = 10 m/hr divided by 2 = an average of 5 m/hr
now 5 m/hr = 1.25 hr
1.25 hr x 5 m/hr = 6.25 miles
Hope that helps, the questions seems a little vague so that's why finding an average of her running speed seems to be the appropriate response.
equate the two distances. distance = speed * time
6t = 4(1.25-t)
6t = 5 - 4t
10t = 5
t = .5
6*.5 = 3
4*.75 = 3
total distance = 6
