In the lead up to the school athletics carnival, Ronald was training with the javelin for three fourths of an hour each day after school due to some rain this week Ronald got 80% of his plan practice. How much hours of practice did Ronald get this week?

Answer 1

Ronald's planned practice time is three fourths of an hour each day after school.
He practiced for 80% of his planned practice time, which is 80/100 * 3/4 = 240/100 hours.
This is equal to 2.4/1 hours. Therefore Ronald practiced for 2.4 hours this week. Answer: \boxed{2.4}.
