Question

a yacht sailing east at a constant velocity took 2 hours to cross half the width of lake nettle. the lake is 320 kilometers wide. what was the yachts velocity? write your answer as a whole number. \boxed{} kilometers per hour to the east submit

Explanation:

Step1: Find half the lake's width

The lake is 320 km wide, so half the width is $\frac{320}{2} = 160$ km.

Step2: Calculate velocity using distance and time

Velocity is distance divided by time. The time is 2 hours, so velocity $v = \frac{160}{2} = 80$ km/h.

Answer:

80
