Alan runs to the gym at a rate a 6 mph. Then he walks home at a rate of 4 mph. IF Alan's home is d miles for the gym, how many hours does it take him to run from his home to the gym?

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

Ibelieve the answer is c i worked it out three times but if my answer is wrong someone correct me
