Answer:
Step-by-step explanation:
Given as :
The distance cover while running = = 5 miles
Let The speed for running =
The distance cover with bike = = 80 miles
The speed for biking = = 15 mph +
Total Time taken = 5 hours
Now Time =
∴ 5 hour = +
Or, 5 hour = +
Or, 5 hour =
or, 5 × () =
Or, - = 0
or, = 0
or, = 0
Or, = 0
Or, = 0
Or, = 0
∴ = 3 , - 5
So, the running speed = 3 mile per hour
And the biking speed = 15 mph + 3 mph = 18 mile per hour
Hence The running speed of Stu is 3 mile per hour . Answer
Answer:
y = -28 ÷ x
Step-by-step explanation:
The standard format of a inversely proportional equation goes by the format of y = k ÷ x. The question asks us to write an equation if y = 7 when x = -4 and y varies inversely with x.
So we substitute the values y = 7 and x = -4 in the equation y = k ÷ x
K = constant, we have to work this out
7 = k ÷ -4
7 × - 4 = k
k = - 4 × 7
k = -28
k = -28 So then we put this back into the original y = k ÷ x to find our final equation which is y = -28 ÷ x
