Answer:
The two trains will leave together at 7 : 02
Step-by-step explanation:
In this problem, we need to find the LCM of 7 and 6
7; 14, 21, 28, 35, 42, 49, 56, 63, 70
6; 12, 18, 24, 30, 36, 42, 48, 54, 60
LCM = 42
6 : 20 + 42 minutes =
6 : 62 ( since 1 hour is equivalent to 60 minutes, 6 : 62 will be 7 : 02)
Answer = The two trains will leave together at 7 : 02
