Question

A man can cover 35/2 km in 5 hours. Find his speed in (a) m/min (b) m/sec.​

Answer 1

Step-by-step explanation:

35/2=17.5 km/5 hours

so 17.5/5= 3.5/ hour=58.3m/min

58.3÷60=0.97166...m/sec

Answer 2

In 1hour= 35/2× 1/5 km/hr

=35/10

=3.5km/hr

(a) in m/min

=3.5×1000/60

=3.5×50/3

=55.34m/min(approx)

(b) in m/sec

=3.5×1000/3600

17.5/18 m/sec
