f) 11 – 8 = 3

g) 20 – 8 = 12

h) 16 – 7 = 9

i) 12 – 9 = 3

j) 21 – 9 = 12

k) 11 – 6 = 5

l) 5 – 5 = 0

m) 4 – 0 = 4

n) 16 – 8 = 8

q) 13 – 8 = 5

r) 12 – 4 = 8

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)
