Answer:
It will take almost 2 hours 8 mins .
Explanation:
The man rides his bicycle for 9 km for 1 hour.
He has to travel 11.54 miles.
1 mile = 1.609 km
11.54 miles= 11.54* 1.609 km= 18.568 = 18.57 km
It will take him 18.57 km / 9 km= 2.06 hrs= 127 mins
He moves 26 minutes at 6.76 km per hour meaning he moves 6.76/60 * 26=
2.93 km .
He moves 10 minutes at 5.55 km per hour meaning he moves 5.55/60 * 10=
0.925 km .
Out of 18.57 km he has moved 2.93+0.925= 3.855 km in 36 mins
18.57 km- 3.9 km = 14. 67 km is yet to travel
Now applying cross product rule
9 km 60 mins
14.67 km ? x
x= 60 * 14.67/9= 97.8 mins
Total time taken will be 26 + 10 + 97.8 mins = 127.8 mins = 2 hours 7 mins
