Answer:
The correct answer to this question is:
the total time taken to complete 5 rounds = 6.534 minutes
Step-by-step explanation:
Given,
A boy is cycling along a square field at a speed of 18 km/hr
∴ speed = 18 km/hr
The area of the square field = 9604 meters
we know,
area of a square = s * s = 9604 m²
s² = 9604 m²
s = √9604 m²
s = 98 m
perimeter = 4 * side
= 4 * 98 m
= 392 m
Hence, perimeter = 392 m
Also given, he needs to complete 5 rounds.sp,
Total distance = 5 * perimeter
= 5 * 392 m
= 1960 m
Total distance = 1960 m = 1.960 km
In 1 hr, he can cover 18 km
In x hr, he can cover 1.960 km
1.960 / 18 = x / 1
x = 0.1089 hr (approximately)
x = 0.1089 * 60 min
x = 6.534 minutes
Hence, the total time taken to complete 5 rounds = 6.534 minutes
