Answer:
50 miles
Step-by-step explanation:
hello,
let's note x the number of miles travelled heading west,
it takes 1 hour to travel 25 miles
so it takes x/25 hours to travel x miles
we know that in total it travels 7 hours so it will travel 7-x/25 hours heading North, then heading North it takes 1 hour to travel 19 miles
so in 7-x/25 hours it travels 19(7-x/25) miles
we can write, as the total distance is 145 miles
![x+19(7-\dfrac{x}{25})=145\\ 25x+3325-19x=3625\\ 6x=300\\ x = 50](https://tex.z-dn.net/?f=x%2B19%287-%5Cdfrac%7Bx%7D%7B25%7D%29%3D145%5C%5C%3C%3D%3E%2025x%2B3325-19x%3D3625%5C%5C%3C%3D%3E%206x%3D300%5C%5C%3C%3D%3E%20x%20%3D%2050)
we can verify
50 miles heading West takes 2 hours
in 5 hours it travels 19*5 = 95 miles
the total is 145 miles
so this is correct
hope this helps
