A perimeter fence is needed around a square area with sides of 75 m each. What is the total length of fencing required?
Answer: 300 m
Perimeter of a square = 4 × side length = 4 × 75 m = 300 m.
Solve: 144 ÷ 12 + 5 × 3 = ?
Answer: 27
Following BEDMAS: 144 ÷ 12 = 12; 5 × 3 = 15; 12 + 15 = 27.
If a helicopter flies at 240 km/h and needs to cover 60 km, how many minutes will the flight take?
Answer: 15 minutes
Time = distance ÷ speed = 60 ÷ 240 = 0.25 hours = 0.25 × 60 = 15 minutes.
