Question

Tom took a trip of 1,300 miles. He traveled by train at 50 miles an hour and the same number of hours by plane at 275 mph. How many hours did the trip take?

Answer 1

Equation:
train distance + plane distance = 1300 miles

50x + 275x = 1300
x(325) = 1300
x = 4 hours
4x2=8
---
The trip took 8 hrs.

Answer 2

1,300 miles ---- 50 miles ----- 275 mile per hour.

↓ --- 1 hour

1,300 - 275 = 1,025  <- 2 hour

1,025 - 275 = 750   <---- 3 hour

750 - 275 =  475    <---- 4 hour

475 - 275 =  200 <--- 5 hour

200 - 50 = 150 <---- 6 hour

150 - 50 = 50 <--- 7 hour

50 - 50 = 0  <----- 8 hour

ANSWER ---->>>>> 8 Hours

All i did was subtract 275 from 1,300 until i wasn't able to, then i switched from subtracting with 275 to 50, and that's how i got my answer. (:
