Step-by-step explanation:

Answer 2

$</u><u>\</u><u>u</u><u>n</u><u>d</u><u>e</u><u>r</u><u>l</u><u>i</u><u>n</u><u>e</u><u>{</u><u>\</u><u>u</u><u>n</u><u>d</u><u>e</u><u>r</u><u>l</u><u>i</u><u>n</u><u>e</u><u>{</u><u>\mathfrak{Answer</u><u>:</u><u>}</u><u>}</u><u>}$

Speed = 6km/hr

$</u><u>\</u><u>u</u><u>n</u><u>d</u><u>e</u><u>r</u><u>l</u><u>i</u><u>n</u><u>e</u><u>{</u><u>\</u><u>u</u><u>n</u><u>d</u><u>e</u><u>r</u><u>l</u><u>i</u><u>n</u><u>e</u><u>{</u><u>\mathfrak{Explanation</u><u>:</u><u>}</u><u>}</u><u>}$

Given:

• Distance = 8 km
• Time = 1 hour 20 min = 4/3 hours

To find:

Speed in km/hr

Solution:

We know that, $\sf{speed = \frac{distance travelled}{time} }$

$\sf{\implies speed = \frac{8}{\frac{4}{3}}}$

$\sf{\implies {speed = {8}×{\frac{4}{3}}}}$

$\therefore{\sf{\fbox{Speed = 6 km /hr}}}$
