They took the train and went 10kms,The equation of their walk is y = 3/4x + 10 Find the distance they were away from home if they walked for 20 hours
-----------------
The implication is the train went North 10 kms, using North as the + y-axis.
y = 3/4x + 10
If x is the time in hours (that should be stated),
--> (20,25)
Assuming "home" is where they started (that should be stated),
d+=+sqrt%2820%5E2+%2B+25%5E2%29+=+sqrt%281025%29
d =~ 32 miles
================================
A poorly stated problem.
