Approximately 39 kmph
58.
t=( total distance I to V) /(sum of speeds of A&D)
total dis=(188+254+228+162)=832 km
D ‘s speed=162/6=27 kmph
total speeds=77+27=104 kmph
time taken by they meet=832/104= 8 hrs

59.
Total distance b\w =188+254+228+162+312+146+182
=1472 km
B’s speed=254/ 5 12/23
=254×23/127
=46 kmph
Time taken by B to travel I to VIII=1472/46=32 hrs
60.
Total distance I to VIII =1472
Time taken by to reach I to VIII= 1472/77=19.11

H’s speed =77+10=87
Time taken by to reach I to VIII=1472/87=16.88
=17
So H reach destination 2 hrs early than A (approx)
