so the acceleration at the direction of the slope is 3/5g then it's all about mathematics imho. it doesn't really matter how much it weighs tbh, since it's frictionless.

Draw a triangle and break the force of gravity into components using trigonomoetry. Knowing the distance and force you can find acceleration which you can use to find time.
