A surfer is moving at a constant velocity of 5.2 m/s north relative to a wave which is pushing him west at a constant velocity of 8.6 m/s toward the beach. The surfer begins at a distance of 41 meters away from the beach. How far north does the surfer make it (in meters) before becoming beached? Round answer to 1 decimal place.

The Goliath birdeater belongs to the tarantula family Theraphosidae. Found in northern South America, it is the largest spider in the world by mass and size, but it is second to the giant huntsman spider by leg-span.

The speed and distances are directly proportional. Use ratios to solve for vertical y-distance. The ratio of x-distance west to y-distance north equals the x-velocity to y-velocity.

x/y = vx/vy

41/y = 8.6/5.2

41/y = 1.65

41/1.65 = y

24.8 m = y
