Question

If a man walks at a speed of 2 km/h and walk a distance of 200 meters. How much time he will take to complete his walk?​

Answer 1

Given

• Man walk at a speed = 2km/h
• Distance covered = 200 m

Find out

• Time taken = ?

Solution

→ speed = 2km/h

→ speed = 2 × 5/18

→ speed = 0.5 m/s

As we know that

→ Time = Distance/speed

→ Time = 200/0.5

→ Time = 400sec

Hence, a man complete his walk in 400s

Additional Information

• Speed = distance/time
• Time = speed × time
• 1km = 1000m
• 1hours = 3600sec

Answer 2

Answer:

Given:-

• speed= 2km/h
• distance=200m

To find:-

• Tme= ....?

Solution:-

Speed of man = 2km/h =

$\frac{2 \times 5}{18} = \frac{10}{18} = \frac{5}{9}$

As we know that,

$speed = \frac{distance}{time} \\ time = \frac{distance}{speed} \\ time = \frac{200m}{ \frac{5}{9} } = \frac{200 \times 9}{5} = 360min$

Hence, it takes 360min = 6hour

Hope its help uh❤
