Explanation:

3600/60=60km/sec

Answer 2

Answer:

$to \: convert \\ 2400sec \: into \: minutes \\ we \: know \: that \: 1min = 60sec \\ so \: 1sec = \frac{1}{60} minutes \\ 2400sec = \frac{2400}{60} min \\ hence \: 4 \: minutes$

$given - \\ distance = 36000km \\ time = 1hr = 3600sec \\ speed = \frac{distance}{time} \\ \: \: \: \: \: \: \: \: \: \: \: \: = \frac{36000}{3600} kms {}^{ - 1} \\ speed = 10kms {}^{ - 1}$
