Two walkers set off at the same time from a crossroad and walk along flat straight roads inclined to each other at 68 degrees.If they both walk at a speed of 6km/h,find their distance apart 10 minutes later.

Answer 1

In 10 minutes they each walk 6/6 = 1km

d^2 = 1^2 + 1^2 - 2(1)(1)cos68°

Answer 2

Find their distance apart in 10 minutes later using the trigonometry ratio

Answer 3

1 kilometer

Answer 4

Correct! The distance between them after 10 minutes is approximately 1 kilometer.
