Answer 2

Answer

Time taken = 30 min

Given

A man walks on a straight road with a speed of 6 km/ hour if he covers a distance of 3 km

To Find

how much time will he take

Solution

Speed , S = 6 km/h

Distance , D = 3 km

Time , t = ? min

We know that , " Speed is defined as distance travelled per unit time "

$\rm Speed=\dfrac{Distance}{Time}\\\\\rm \to\ S=\dfrac{D}{t}\\\\\rm \to\ 6=\dfrac{3}{t}\\\\\rm \to\ t=\dfrac{3}{6}\\\\\rm \to\ t=\dfrac{1}{2}\\\\\rm \to\ t=0.5\ h\\\\\rm \to\ t=30\ m\ \; \bigstar$
