Problema Solution
Each day, I walk 24 km from home to work at a constant speed. After I have gone 8 km from home, I am at the bank; today the clock at the bank reads 7:52 AM. After having walked a total of 18 km, I am at the store; today the clock at the store reads 8:02 AM. At what time was I halfway to work?
Answer provided by our tutors
7:52 at the 8 km mark
8:02 at the 18 km mark
12 km is the halfway point
8:02 - 7:52 = 10 minutes
18-8 = 10 km
1 km/minute
12 - 8 = 4
so 4 minutes past 7:52 is the halfway point - you were halfway to work at 07:56
