70%*X+160=110%*X
0.4*X=160
X=400

1. There is a clock, which is one minute slower than the standard time every hour. It is 12:00 at noon. The slow clock in the afternoon refers to 6:00. What is the standard time in the afternoon?
2. It's 3 p.m. now. When will the hour hand and the minute hand coincide for the first time?
3. Xiao Ming aims his watch at 9 o'clock in the evening, but he is 10 minutes late when he arrives at school at 8 o'clock the next morning. How many minutes is Xiao Ming's watch slow?
4. Xiaoming's wall clock is 2 minutes slow every hour. At 8 a.m., Xiaoming sets the wall clock at the standard time. When does the wall clock go to 12 noon, what's the standard time?
5. How many minutes after 3 o'clock. The force of the hour hand and minute hand from "3" is equal, and on both sides of "3"?

1. Every hour is one minute slower than the standard, so one hour of the clock is equivalent to the standard 60 / 59 hour, so the time after six hours is 60 / 59 * 6, which is about 6:6 of the standard time. 2

When a cartoon was shown for less than an hour, Gao Xinxin found that the positions of the hour hand and the minute hand on the watch at the end of the show were exchanged with the positions of the minute hand and the hour hand at the beginning of the show. He asked: how long has the cartoon been shown?

The degrees of the hour hand per minute are: 360 °△ 60 × 5 △ 60, = 60 °× 5 △ 60, = 0.5 ° and the degrees of the minute hand per minute are: 360 °△ 60 = 6 ° the positions of the hour hand and the minute hand on the watch and the positions of the minute hand and the hour hand at the beginning are: 360 °△ 0.5 ° + 6 °, = 360 °△ 6.5 ° and = 55513 (minutes). A: this cartoon shows 55513 minutes
