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

Answer:
x=-4
Step-by-step explanation:
First, distribute the 4
this makes 4x + 36 = 20
Then, subtract 36 to combine like terms. 4x = -16
divide 4x! x = -4
Answer:
a. y = 3.
b. y = -2.
Step-by-step explanation:
a. Parallel to y = 0 means parallel to the x- axis ( y = 0 is the x axis). The equation will be of the form y = something.
As it passes through the point (-3,3) it must therefore be y = 3.
b. Perpendicular to x = 0 means perpendicular to the y axis so the equation will be y = -2 (because it passes through (5, -2).
Answer:
B
