first convert 400.000 m to km, 400 km
80 km /h x 5h= 400km
so it going to take 5 hours of travel
Answer:
5 hours
Step-by-step explanation:
Enter your answer in the box.
y-ordinate of x-intercept is 0 .Putting y = 0 in the equation we get 1 3 x + 0 = − 15 or 1 3 x = − 15 or x = − ( 3 ⋅ 15 ) = − 45 ∴ x=intercept is ( − 45 , 0 ) graph{-1/3x-15 [-80, 80, -40, 40]}[Ans]
Hope this helped.
Your answer:
x-intercept is ( -45 , 0 )
Answer:
To find the x-intercept, substitute in 0 for y and solve for x. To find the y-intercept, substitute in 0 for x and solve for y.
x-intercept: (−45,0)
y-intercept: (0,−15)
