Acheetah can travel up to 29 meters per second. what is the cheetahs speed to the nearest tenth in miles per hour? (1 mile=1690 meters)

1690 meters = 1 mile
29 meters = 29/1690 = 0.01716 miles

1 second = 1/3600 = 0.000278 hours

29 meters/1 seconds = 0.01716 miles/0.000278 hours = 61.8 miles per hour.

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post

I’m not sure about that
