Question

A Person Completes 1 round(s) In A Square Field Of Side 7m In 50s. Find the distance travelled by him After 4 Minutes and 10 Seconds. (2 MARKS)

Answer 1

Answer:

140m

Explanation:

Person completes 1 round in 50 s.

Here, 1 round of square means travelling through all of its sides.

Means,

Distance in one round = perimeter of square

Distance in 1 round = 4 * side of square = 4 * 7 m

Distance in 1 round = 28 m

It means, he covers 28 m in 50 s.

= > 28 m in 50 s

= > (28/50) m in 1s

As 4 min 10 sec = 4(60) s + 10 s = 250 s, we will multiply both sides by 250.

= > (28/50)*250 m in 250 s

= > (28*5) m in 250s

= > 140 m in 250 s

Therefore,

He covers 140m in 4min 10s.

Answer 2

Answer:

The total distance covered by the person is

140 m.

Explanation:

The distance covered in 1 round

= 4 × 7 ( 4 × S)

= 28 m.

Now the rounds covered by the person in 4 min 10 sec

= 250 sec ÷ 50 sec

= 5 rounds.

Therefore , total distance covered by the person is

= 5 × 28 m

= 140 m.
