On Thursday she cycled 88 km per hr...for 4 hrs
88/4 = 22 km per hr

22 + 3 = 25 km per hr <==
Answer:
.83333333 or 5/6
Step-by-step explanation:
Make common denominator
204/468 + 429/468 = 633/468 - (195/468 + 48/468)
Simplify: 633/468 - 243/468
390/468 can be further broken down to 5/6 if you divide by a common factor which is 78.
Answer:
y = - 10
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 2 when x = - 4, that is
2 = - 4k ( divide both sides by - 4 )
= k, that is
k = -
y = - x ← equation of variation
When x = 20, then
y = - × 20 = - 10
