Question

Two walkers set off at the same time from a crossroad and walk along flat straight roads incline to each other at 70°.If they both walk at a speed of 8km/h, find their distance apart 10 minutes latater

[AI-generated answer — Bot GPT 3.5]

After 10 minutes, both walkers will have traveled a distance of 8 km/h x (10/60)h = 1.33 km each.

Since they are walking at an angle of 70° to each other, we can consider the triangle formed by the two walkers and the distance between them as a right triangle.

Using trigonometry, we can find the distance between the two walkers after 10 minutes:

Let x be the distance between the two walkers after 10 minutes.

sin(70°) = x / 1.33 km
x = 1.33 km * sin(70°)
x ≈ 1.27 km

Therefore, after 10 minutes, the two walkers are approximately 1.27 km apart.
