Question

warren is paddling his kayak across the widest part of lake spollo, which is 810 meters wide from west to east. he is moving at a constant velocity of 90 meters per minute to the east. how much time will it take warren to paddle one-third of the way across the lake? write your answer as a whole number.
□ minutes

Explanation:

Step1: Find one - third of the lake's width

The width of the lake is 810 meters. One - third of 810 meters is calculated as $\frac{1}{3}\times810 = 270$ meters.

Step2: Use the formula $time=\frac{distance}{velocity}$

We know that the velocity $v = 90$ meters per minute and the distance $d=270$ meters.
Using the formula $t=\frac{d}{v}$, we substitute $d = 270$ and $v=90$ into it. So $t=\frac{270}{90}=3$ minutes.
