The statistical chart is the broadcast time of four programs in a TV station for four months. Assuming that the same program is broadcast at the same time every month, how long does each program last every month?

Monthly broadcast time of news: 340÷4=85 (hours), sports: 180÷4=45 (hours), cartoons: 120÷4=30 (hours), and TV dramas: 240.

The purpose of this problem is to consolidate the division in which the divisor is a single digit, and at the same time, set up doubts and lead to the bar chart to be learned.
