Question

Ethan goes on a charlity journey.he walks oone tenth of the way at 6 km/h,runs one sixth at 12 km/h,cycles one fifth at 24 km/h,and completes the remaining 32 km by car at 48 km/h.how many kilometers does he travel and how long does it take??

Answer 1

???????????? "journee" ???? "travel" ????????? yu must meen him GO

(1/10)+(1/6) +(1/5)=(3/30)+(5/30)+(6/30)=(14/30)

so rest av wae=16/30=32 km

so distans=30*32/16=60km

last part...32km / 48(km/our)=(2/3)our=40 minuts

part1...(1/10)=6km/6(km/our)=1 our

part2...(1/6)=10km, time=10/12 our=50 minuts

part3...(1/5)=12km/24=0.5our=30min

time=1 our+40+50+30min=180 minuts=3 ours

60km/3ours...averaej speed=20km/our
