Subtract today’s readings from yesterday’s total: 200 - 150 = 50.
Calculate 75% of 80: (75/100) × 80 = 60.
Estimate by dividing total meters by meters per hour: 235 ÷ 50 ≈ 4.7 hours, which rounds to 5 hours.
Multiply the number of blocks by meters per block: 12 × 15 = 180.
Simply add the two numbers: 125 + 78 = 193.
