----------------------------------------
Convert hours to minutes
----------------------------------------
1 hour 55 mins = 60 + 55 = 115 mins
1 hour 50 mins = 60 + 50 = 110 mins

_____________________________________________________

----------------------------------------
Speed = 36/h
----------------------------------------
1 hour = 36 km

----------------------------------------
Rewrite 1 hour as 60 mins
----------------------------------------
60 mins = 36 km

----------------------------------------
Find 1 min
----------------------------------------
1 min = 36 ÷ 60
1 min = 0.6 km

----------------------------------------
Find 115 mins
----------------------------------------
1 min = 0.6 km
115 min = 0.6 x 115
115 min = 69km

----------------------------------------
Speed = 72km/h
----------------------------------------
1 hour = 72 km

----------------------------------------
Write 1 hour as 60 mins
----------------------------------------
60 mins = 72 km

----------------------------------------
Find 1 min
----------------------------------------
1 min = 72 ÷ 60
1 min = 1.2 km

----------------------------------------
Find 110 min
----------------------------------------
1 min = 1.2 km
110 min = 1.2 x 110
110 min = 132 km

----------------------------------------
Total Distance traveled:
----------------------------------------
69km + 132km = 201km

----------------------------------------
Answer: 201 km
