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
A train averages a speed of 90 miles per hour across the plains and 37.5 miles per hour through the mountains. If a trip of 300 miles took 3 hour and 48 minutes, how much of it was through the mountains?

HEY DADDY
you can find the mile by doing these easy steps:
48=0.8
37.5*0.8=30 miles
30 miles is the correct answer
48=0.8
37.5*0.8=30 miles
30 miles is the correct answer
48
48 bc i did the equation and got it
