Jodie ran at an average speed of 9 km/h for 40 minutes. How far did she run in km?

2 answers:

8 0

Answer: 6km

Explanation:
By using the formula d=v x t
And knowing:
V=9km/h
t= 40 min = 2/3hr
We get an equation:
d= 9 x 2/3 = 6km

Answer:

6 km

Step-by-step explanation:

40 min = 40/60 h = 4/6 h = 2/3 h

1 h ................. 9 km

2/3 h ..............x km

x = 2/3×9km = 18/3 km = 6 km

Solve the initial value problem. dy/dt = 1 + 6/t , t > 0, y = 8 when t = 1

nordsb [41]

$\displaystyle\frac{dy}{dt} = 1 + \frac{6}{t}\ \Rightarrow\ dy = \left( 1 + \frac{6}{t}\right) dt\ \Rightarrow\int 1\, dy = \int \left( 1 + \frac{6}{t}\right) dt \ \Rightarrow \\ \\
y = t + 6\ln|t| + C. \text{ But $t\ \textgreater \ 0$ so }y = t + 6\ln t + C. \\ \\ 
y(1) = 8\ \Rightarrow\ 8 = 1 + 6 \ln 1 + C \ \Rightarrow\ C = 7 \text{ so } \\ \\
y(t) = t + 6\ln t + 7$
