Answer: each 0.5 hour or 30 minutes they travel 1 mile
Step-by-step explanation:
so just keep adding 1 mile each 0.5 hour
First car is x
second car is y
25x+30y=1550
x+y=55
Multiply the second equation by -25 for elimination method to cancel out x
-25x-25y=-1375
Add the two equations
5y=175
y=35
Plug this value into the second equation
x+35=55
x=20
Final answers:
First car=20 gallons
Second car=35 gallons
Tan θ=opposite/adjacent
= 4/3
=1.333
I’m not sure if that’s how it’s done but…
