Question

the time taken to run around a square field of area 16900 sq m at a speed of 13 km/h is​

Answer 1

Answer:

1300

Step-by-step explanation:

time = distance by speed

t = d/s

t = 16900/13

t = 1300

Answer 2

Step-by-step explanation:

$\bf{\underline{\underline\pink{Question}}}$

The time taken to run around a square field of area 16900

sq m at a speed of 13 km/h ??

$\bf{\underline{\underline\red{To \: find}}}$

The time taken to run around a square field

$\bf{\Underline{\underline\violent{Solution}}}$

time = t

area = 16900 m²

Area of square field = side² = 16900m²

therefore side = $\sqrt{16900}$ m

= 130 m

= 0.130 km

speed = 13 km/h

speed = distance/ time

time = distance/ speed

time = $\frac{0.130}{13}$

time = 0.01 h

time = 36 sec.
