Question

A man walks 5 minutes towards north at a rate of 15 steps per minute.he then walks
towards south at the same speed. How far will be after 2 minutes from the starting
point?
​

Answer 1

Answer:-

45 steps

Explanation:-

Given:-

A man walks towards,

• North for 5 min at a rate of 15 steps/min
• South for 2 min with the same speed

To Find:-

Distance of the man after two minutes from the starting point.

Solution:-

Distance travelled by the man in North Direction(d):-

Distance = Speed × time

d = 15 × 15

d = 75 steps

Distance travelled by the man in South Direction(d'):-

d' = 15 × 2

d' = 30 steps

Distance from starting point (D):-

${\rightarrow}D = d - d'$

${\rightarrow}D = 75 - 30$

${\rightarrow}D = 45 steps$

Answer 2

${\bold{\underline{\underline{Answer:}}}}$

${\bold{\therefore Distance\:from\:starting\:point=45\:steps}}$

${\bold{\underline{\underline{Step-by-step\:explanation:}}}}$

• In the given question information given about a man walks 5 minutes towards north at a rate of 15 steps per minute.he then walks towards south at the same speed.

• We have to find the distance travelled after 2 minutes from starting point.

$\underline \bold{Given : } \\ \implies Speed = 15 \: steps /min \\ \\ \implies Time = 5 \: minutes \\ \\ \implies Direction = North \to South \\ \\ \underline \bold{To \: Find : } \\ \implies Distance \: after \: 2 \: min \: from \: starting \: point = ?$

• According to given question :

$\bold{In \: North \: direction : } \\ \implies Distance = Speed \times Time \\ \\ \implies D= 15 \times 5 \\ \\ \bold{\implies D = 75 \: steps} \\ \\ \bold{In \: South \: direction : } \\ \implies Time = 2 \: min \\ \\ \implies D = S \times T \\ \\ \implies D= 15 \times 2 \\ \\ \bold{\implies D= 30 \: steps} \\ \\ \bold{Distance \: from \: starting \: point} \\ \implies 75 - 30 \\ \\ \bold{\implies 45 \: steps } \\ \\ \bold{\therefore Man \: is \: 45 \: steps \: away \: in } \\ \: \: \: \: \bold{ North \: direction \: from \: starting \: point}$
