Answer:
Distance traveled 17.5 kilometers
Step-by-step explanation:
We can use the following equation to find the distance traveled,
Distance traveled = Speed * Time
First we need to find the total time he walked = 2.30 p.m. - 11.a.m.
= hours
Now we can substitute the values to the equation,
Distance traveled = kilometers per hour *
hours
= kilometers
= 17.5 kilometers
(1) y = 7x , (2) y = 11x , (3) y = 9x , (4) y = 28x
given y varies directly as x then y = kx ( k is the constant of variation )
(1) find k using the given conditions k = =
= 7
equation is y = 7x
(2) k = = 11
equation is y = 11x
(3) k = = 9
equation is y = 9x
(4) k = = 28
equation is y = 28x
