Question 930522
x = time traveled at 56 mph
y = time traveled at 48 mph
a = distance traveled at 56 mph
b = distance traveled at 56 mph
---
s = d/t
d = st
---
distance traveled at 56 mph:
a = 56x
---
distance traveled at 56 mph:
b = 48y
---
total distance:
a + b = 128
56x + 48y = 128
---
total time:
x + y = 2.5
---
put the system of linear equations into standard form
---
56x + 48y = 128
x + y = 2.5
---
