Answer 6

im confused

Answer 7

First convert Km per hour to meters per second

27 KM/h = 27,000 m /h because there is 1000m in a km.
Divide this by 3600 to give m / s (because there is 3600 seconds in an hour)

so 27 km/h = 27000 / 3600 m / s


Now convert 14 dm /s to m / s

here we just divide by 10 because 1 m = 10 dm

This comes to 1.40 m / s



so the difference is (27,000 / 3600) - 1.40

work that out and you have the answer

Note do the division in the paremtheses first

Answer 8

6.1

Answer 9

7.5 - 1.4 = 6.1 m/s
