Question

guys please answer fast it's urgent with full solution​

Answer 1

Answer:

speed = distance/time

speed in km/min = 6km/30min

0.2km/min

now min in hour = 30/60

=1/2

speed in km/hour = 6km/1/2hour

= 12km/hour

speed in metre/second = 6×1000/30×60

$6000 \div 1800 =10 \div 3 = 3.33 \: metre \sec$

Answer 2

Time= 30 minutes
= 1800 seconds
= 1/2 hour
Distance= 6 km
= 6000 m
Speed= distance/time
(i) speed=6/30
= 0.2 km/min
(ii) speed= 6/0.5
=12 km/hr
(iii) speed= 6000/1800
= 3.33 m/s (bar on 3)
