Step-by-step explanation: The second hand on a clock rotates around the center of a clock creating a circle. This means it travels around the circle of the clock every hour. Its distance around the clock is the circumference of its circle with radius 8 cm.
This is the total distance around the clock in 1 hour. But how far does it travel in 10 minutes? 10 minutes is 1/6 of 60 minutes, a full hour. Multiply the circumference by 1/6 to find the distance in 10 minutes.
contradiction : Neither of the 2 items that Val bought cost more then $ 15
think about it....if neither of them cost more then 15....lets say they cost 15 each...then there is no way he spent $ 34.....he would spend at most $ 30
