Average speed in m/min is 24m/min
Average speed in m/sec is 0.4m/sec
Explanation:
Given:
Distance, x = 420m
Time, t = 17.5 min
Average speed in m/min and m/s
Average speed in m/min = [tex]\frac{distance}{time}[/tex]
= [tex]\frac{420}{17.5}[/tex]
= 24 m/min
Average speed in m/sec = [tex]\frac{distance}{time}[/tex]
= [tex]\frac{420}{17.5 X 60}[/tex]
= 0.4 m/sec
