please solve my problem who solve this i will give 100 points it my open challenge for every brainly member ​

Answer 1

$\huge\star{\blue{\underline{\mathfrak{Answer}}}}$

(d)8 km/h

$\huge{\red{\underline{\mathfrak{Solution}}}}$

In 6 minutes, the walking man covered a distance of

$(6 \times 2) \div 60$

$= 12 \div 60$

$= 0.2 \: km$

During the 6 minutes ,the distance travelled by car

$= 0.2+0.6=0.8 kms$

So speed of car

$=( 0.8 \times 60)/6$

$\huge\boxed{\blue{\underline{\mathfrak{ = 8 km/hr}}}}$

Answer 2

in 6 minutes the car goes ahead by 0.6km

hence,the relative speed of the car with respect to the pedestrian is equal to 6kmph

hence net speed of the car is 8 kmph since speed of car (6kmph) and pedestrian (2kmph) gets add up as they move in same direction

thus answer is option d .8kmph

hope it helps..
