Answer 2

Answer:

     time = 382 seconds

Step-by-step explanation:

Area of the square = side² = 9604 m²

side² = 9604 m²

side = √9604 m²

side = 98 m

perimeter of square = 4 × 98m = 382m

total distance travelled = 5 × 382 = 1910m

speed = 18 km/hr = 18 × 5 / 18 m/s = 5m/s

time = distance / speed

time = 1910 / 5
