Question

anonymous · Answer

Try drawing a picture first, then set up some distance = rate × time equations.

anonymous · Answer

does the question give you the distance he traveled?

anonymous · Answer

the speed of jogging is twice when jim goes to park than that of returning, then the time taken to go to park will be half of the time taken to return
total time is 1.5 hours
so, time to go to park= .5 hours=30 minutes

This one is pretty easy to guess-and-check at using proportional thinking.
The set up is to use d=r*t twice. The distance, d, is the same both ways, so 
r1*t1 = r2*t2
The total time is 1.5 hours, so
t1 + t2 = 1.5
r1 and r2 are given, so this can be solved with substitution.
