Dear friend,
Speed1 = 6 km/hr
Time1 = 2 hrs
Distance1 = Speed1 × Time1
= 6 × 2 km = 12 km
Speed2 = 4 km/hr
Time2 = 3hrs
Distance2 = Speed2 × Time2
= 4 × 3 km = 12 km
Total distance moved = 12 km + 12 km
= 24 km
Average speed = (Speed1 + Speed2) / 2
= (6+4) / 2 = 10 / 2 = 5 km/hr
Answer: (i) Total distance moved is 24 km.
(ii) Average speed = 5 km/hr
Hope it helps !!!
