Question 363068
Two bicyclists, starting at the same place, are riding toward the same
 campground by two different routes.
 One cyclist rides 1070 m due east and then turns due north and travels
 another 1430 m before reaching the campground.
 The second cyclist starts out by heading due north for 1800 m and then
 turns and heads directly toward the campground.
At the turning point, how far is the second cyclist from the campground?
:
Draw the diagram of this, it will be apparent that a right triangle is formed:
side 1 = 1070
side 2: 1800 - 1430 = 370
Hypotenuse (h) = 2nd cyclist turning point to camp ground
h = {{{sqrt(1070^2 + 370^2)}}}
h = 1132.166 meter from turning point to camp ground
