Question

perimeter =344 m rate of walking = 4km/h so how much time taken to cover 3 rounds of a rectangular park.​

Answer 1

Step-by-step explanation:

Perimeter can also be called the distance travelled in one round.

So distance traveled in 3 rounds = 344 × 3 = 1032 m = 1.032 km

$speed \: = \frac{distance}{time} \\ so \: time \: = \frac{distance}{speed} \\ = 1.032 \div 4 = 0.258 \: hours \: \\ \\ 0.258 \: hours \: = 0.258 \times 60 = 15.48 \: minutes$

Answer 2

Answer:

15.48 minute

*Explantion*

Perimeter of the rectangular park=344m

Total distance=(344×3)=1032m

The speed of running=4km/h

=(4×1000)m/h=4000m/h

The man/women runs 4000m in 1 hour i.e in 60 min

The man/women runs 1 m in 60/4000 min

The man/women runs 1032m

Ans-The time required is (1032×60/4000)=15.48 min
