Answer: The speed of her walking is 4 mph and the speed of her jogging is 6 mph.

Explanation:

Since we have given that

Time taken by Lorena to walk the path = 30 minutes

Time taken by Loren to jogs the path = 20 minutes

Let the speed of her walking be 'x'.

Let the speed of her jogging be 'x+2'.

Since distance would remain same, so it becomes,


30x=20(x+2)\\\\30x=20x+40\\\\30x-20x=40\\\\10x=40\\\\x=(40)/(10)\\\\x=4\ mph

Hence, the speed of her walking is 4 mph and the speed of her jogging is 6 mph.
