As the graph shows,z(3,4),w(-4,1)
so,w-z(-4-3,1-4)⇒(-7,-3)
z-w(3-(-4),4-1)⇒(3+4,3)⇒(7,3).
You'll reach destination in 1.6 days or rounded to 2 days.
->calculate how much did you pass already 1250×5/7=892 miles traveled (rounded)
->then calculate how much miles you have to go
1250-892=358 miles left to travel
->then calculate speed at which you travel
892/4(how much days you traveled already)=223miles per day
->then just divide miles left with speed
358/223=1.6 or 2 days left to reaching destination.
I can only help you if you give me a lot of points
The length of a table, the width of a classroom, and the length of a car can be easily measured without using trigonometry (could probably use a meter stick or measuring tape) because we can easily reach both ends
the width of a wide river is a little different, it may not be practical to measure the distance across directly.
