Matthew was 1200 yards when Lowe began his pursuit. If Lowe ran 3 times as fast as Matthew, and overtook him in 30 minutes, how
antiseptic1488 [7]

Idk if this wil help but...



Let speed of Matthew be X yards/min  Speed of Lowe = 3X yards/min.


Distance covered by Matthew in 30 minutes = 30X


Distance covered by Lowe in 30 minutes = 30(3X)= 90X


90X = 30X + 1200       X = 20 yards/min

Let speed of Matthew be X yards/min  Speed of Lowe = 3X yards/min.


Distance covered by Matthew in 30 minutes = 30X


Distance covered by Lowe in 30 minutes = 30(3X)= 90X


90X = 30X + 1200       X = 20 yards/min
