Answer 1

a) 0.72 h

b) 3 days

c) 7.2 hours

d) 0.072 h

Answer 2

As per the data given in the above question.

In the above question, it is given that,

The given data is 12m/min,

We have to convert the given data in km/hr​.

Thus, solving the equation we get,

1m = 0.001km

1 hour = 60minutes,

Therefore 12 m/min in km/hr as bellow,

$=\frac{0.001}{\frac{1}{60} } \times 12\\=0.72km/hr$

Hence the converted value is 0.72km/hr
