A man walks 6 km at 12 km/h and returns at 10 km/h. Find his average speed
Answers
Step-by-step explanation:
Speed =6km/h
Speed =6km/h
Speed =6km/h distance =1km
Speed =6km/h distance =1km
Speed =6km/h distance =1km Time =distance/speed=1/6h
Speed =6km/h distance =1km Time =distance/speed=1/6h
Speed =6km/h distance =1km Time =distance/speed=1/6h
Speed =6km/h distance =1km Time =distance/speed=1/6h Speed =8km/h
Speed =6km/h distance =1km Time =distance/speed=1/6h Speed =8km/h
Speed =6km/h distance =1km Time =distance/speed=1/6h Speed =8km/h Distance =1km
Speed =6km/h distance =1km Time =distance/speed=1/6h Speed =8km/h Distance =1km
Speed =6km/h distance =1km Time =distance/speed=1/6h Speed =8km/h Distance =1km Time =distance/speed=1/8h
Speed =6km/h distance =1km Time =distance/speed=1/6h Speed =8km/h Distance =1km Time =distance/speed=1/8h
Speed =6km/h distance =1km Time =distance/speed=1/6h Speed =8km/h Distance =1km Time =distance/speed=1/8h Average speed =Totaldistance/totaltimetaken
Speed =6km/h distance =1km Time =distance/speed=1/6h Speed =8km/h Distance =1km Time =distance/speed=1/8h Average speed =Totaldistance/totaltimetaken =1+1+61+81
Speed =6km/h distance =1km Time =distance/speed=1/6h Speed =8km/h Distance =1km Time =distance/speed=1/8h Average speed =Totaldistance/totaltimetaken =1+1+61+81 =2+244+3
Speed =6km/h distance =1km Time =distance/speed=1/6h Speed =8km/h Distance =1km Time =distance/speed=1/8h Average speed =Totaldistance/totaltimetaken =1+1+61+81 =2+244+3=2+247=2×724=748
Speed =6km/h distance =1km Time =distance/speed=1/6h Speed =8km/h Distance =1km Time =distance/speed=1/8h Average speed =Totaldistance/totaltimetaken =1+1+61+81 =2+244+3=2+247=2×724=748 =6.85km/h
