Problema Solution
At 9:00 A.M. your friends begin hiking at 2 mi/h. You begin from the same place at 9:25 A.M.You hike 3 mi/h. How long will you have hiked when you catch up with your friends?
Answer provided by our tutors
Let t = number of hours until you catch up with them:
But they went ahead of you by 25 min. Therefore, they are 2*25/60 miles ahead of you when you began to hike.
2t + 2*25/60 = 3t
t = 50/60 hours
= 50 minutes.
You will catch up with them after 50 minutes, or 10:15 AM
