Here is your answer ==>
Speed =30 km per hour

time teken to cover 375 km = 12 hours 30 minutes (12 hour foe 3600 km and 30 min for 15 km)

time stopped =>2 hour (75,km,150 km,225km,300km=4 times)

30minute× 4= 120 min=2 hour

total time to teken to complete the journey =12 hour 30 min+2hour=14hour 30 min ......answer

hope it's help you !!!

Answer 2

Find total time on the motorcycle:

30 km = 1 hour

1 km = 1/30 hour

375 = 1/30 x 375 = 12.5 hours

Find the total time for his break:

Total number of 75km  = 375 ÷ 75 = 5

Total number of breaks = 5 - 1 = 4

(We do not count in the last break when he has already reached his destination)

Total break time = 4 x 1/2 = 2 hours

Find total Duration:

12.5 + 2 = 14.5 hours

Answer: It will take him 14.5 hours to cover 375 km.
