Question

plzzzz answer me in briefly

Answer 1

110 minutes and 125 hours

Answer 2

Time taken by a train to travel = 1 hour 20 minutes = 80 minutes [ 1 hour = 60 minutes]
speed of the train = 60 KMPH
speed of the train in minutes = 60 KMPH × 1000/60 [ 1km = 1000m & 1 hour =60 mins]
= 60 KMPH × 50/3
= 3000/3 m per min
= 1000 metres per minute
= 1 km per minute
distance travelled in the train = 1 kmpm × 80 min
= 80 kilometres
Time taken by a bus = 54 minutes
speed of the bus = 50 kmph
speed of the bus in minutes = 50 kmph × 50 /3
= 2500/3 mpm [mpm = metres per minutes]
= 833 1/3 mpm
distance travelled in the bus = 833 1/3 mpm × 54 minutes
= 833 m × 18
= 14994 m
= 14.994 km
time take by a boat = 1 hour 36 minutes = 96 minutes
speed of the boat = 15 kmph
speed of the boat in minutes = 15 kmph × 50/3
= 5 kmph × 50
=250 mpm
= 0.250 mpm
distance travelled in a boat = 0.250 mpm × 96 minutes
= 24 km
total distance travelled by him = 80 km + 14.994 km + 24 km = 118.994 km
