Kendra jogs 2 2/5 km on a trail and then sits down to wait for louis. louis has jogged 1 1/2 km on the same trail. how much fart
agasfer [191]
To determine the answer to this question, we simply subtract the distance already covered by Louis from the distance covered by Kendra. Mathematically,
                                 distance = 2 2/5 km - 1 1/2 km
                                               = 9/10 km
Thus, Louis still need to jog 9/10 km to reach Kendra.
