Greg is bowling with his friends and rolls the ball at time . Consider the center axis of the lane to correspond to line and the pin deck to be at the line . The gutters correspond to the lines and $ ...
There is not enough information to determine whether Greg’s ball will reach the pins before the gutters.
Greg’s ball will reach the pins and the gutters at the same time.
No, Greg’s ball will roll into the gutters before reaching any pins.
Yes, Greg’s ball will reach the pins before the gutters.
