Xiaoqiang travels 5 / 3 kilometers in 1 / 3 hour. According to this calculation, he can travel thousands of meters in an hour, and how many hours does it take to travel a kilometer

V*1/3=5/3
V = 5km / h
You can walk 5 kilometers an hour
It takes one fifth of an hour to travel one kilometer

Xiaoqiang walks 5 / 12 kilometers in 1 / 5 hour. How many hours does it take for him to walk one kilometer

25/12

Simple calculation: (6.5 × 0.68 × 2.28) / (1.3 × 1.7 × 0.28)

(6.5×0.68×2.28)÷(1.3×1.7×0.19)
=6.5÷1.3x0.68÷1.7x2.28÷0.19
＝5x0.4x12
=24

Simple operation of 1 + 3 + 5 + 7 to 19

Simple calculation of 4.86 times 9.9 simple calculation of 4.9 times 1.02 simple calculation of 3.84 times 9.6 + 0.96 times 61.6

4.86× 9.9
=4.86×10-4.86×0.1
=48.6-0.486
=48.114
4.9×1.02
=5×1.02-0.1×1.02
=5.1-0.102
=4.998
3.84 times 9.6 + 0.96 times 61.6
=3.84×9.6+9.6×6.16
=9.6×（3.84+6.16）
=9.6×10
=96

Simple calculation of 61 * 4 + 610 + 59 * 61

61*4+610+59*61
=61*4+61*10+59*61
=61*(4+10+59)
=61*73
=4453
