1. 3 hours and 48 minutes = 228 minutes = 8 hours
90x + 37,5y = 300
x + y = 3.8
equations two unknowns
x = 3
y = 0.8
= > 3 hours away on the plains
= > 0.8 hours to go through the mountains
0.8 hours = 0,8.60 = 48 minutes

2. sorry, I typed wrong
3 hours and 48 minutes = 228 minutes = 3,8 hours
90x + 37,5y = 300
x + y = 3.8 [(sorry)]
equations two unknowns
x = 3
y = 0.8
= > 3 hours away on the plains
= > 0.8 hours to go through the mountains
0.8 hours = 0,8.60 = 48 minutes
