3.30× 6 =180km180x1/5 = 36km/h.

180 ÷ 36 = 5 (hours)

A: It can be reached in 5 hours.

4.145+174 = 319 (km) 319 ÷1= 29 (km/h)

145 ÷ 29 = 5 (hours) 1 1-5 = 6 (hours)

A: The first day is 5 o'clock, and the next day is 6 o'clock.

5. 75× 3/5 = 45 (person) 1- 10% = 90%.

45 ÷ 90% = 50 (person)

6、 1-60%=40% 40%+4%=44%

12 10 ÷ 44% = 2750 (ton)

2750× 104% = 2860 (ton)
