Answer:
The answer to your question is: time = 4 hours
Step-by-step explanation:
Data
Total distance = 1300 miles
train v = 50 mi/h time is the same distance = x
plane v = 275 mi/h distance = 1300 - x
t = ?
Formula
v = d/t
Process
Train t = d/v t = x / 50
Plane t = d/ v t = (1300 - x) / 275
x / 50 = (1300 - x) / 275
275 x = 50 (1300 - x)
275 x = 65000 - 50x solve for x
275x + 50x = 65000
325x = 65000
x = 65000/325
x = 200
Time with train
t = 200 / 50 = 4 hours
Time with plane
t = (1300 - 200) / 275
t = 1100 / 275 = 4 hours
Let the number of hours traveled by train be "x".
The x = the number of hours traveled by plane.
-------------------------------------------------
Equation:
train distance + plane distance = 1300 miles
50x + 275x = 1300
x(325) = 1300
x = 4 hours
---
The trip took 8 hrs.
Trust me
2 hours
Let's denote the amount of time we need to find out, t.
=> 600 + 50t < 500 + 100t
or 600 - 500 < 100t - 50t
or 100 < 50t
or 100/50 < t
or t > 2
=> After 2 hours, company B will be cheaper option than company A
