Question

lake nettle is 360 kilometers wide from east to west. a yacht is sailing on the lake at a constant velocity of 90 kilometers per hour to the west. how much time will it take the yacht to sail half of the width of the lake? write your answer as a whole number. hours

Explanation:

Step1: Find half the lake's width

The lake is 360 kilometers wide, so half the width is $\frac{360}{2} = 180$ kilometers.

Step2: Calculate time using speed formula

The formula for time is $time = \frac{distance}{speed}$. The speed is 90 km/h and the distance is 180 km. So $time = \frac{180}{90} = 2$ hours.
