Let the distance from A to B be x km, and the distance from B to C be (240 - x) km. Time taken to travel from A to B = x / 60, Time taken to travel from B to C = (240 - x) / 80. The total time taken is 3.5 hours, so: x / 60 + (240 - x) / 80 = 3.5. Multiply through by 240 (LCM of 60 and 80) to eliminate the denominators: 4x + 3(240 - x) = 840, 4x + 720 - 3x = 840, x = 120. Thus, the distance between B and C is 240-120 = 120 km.
√2703.88 × √784.15 – 26² = ? - (34.85)²
√92.10 + √256.30 + 60.78% of (420.90 + 19.36% of 140.25) = ?
25.09 × (√15 + 19.83) = ? of 19.87 ÷ 4.03
Direction: Please solve the following expression and choose the closest option
52.08% of 645.92 + 1840% of 47.96 = ?
19.99% of 79.98 = ?2– 159.99% of 12.5
19.97% of 3/5 ÷ (1 ÷ 74.99) = ?
30.22% of (61.9 × 5.01) + 69.97 =?
1199.98 ÷ 40.48 × 20.12 = ? × 3.16
88% of 900.23 + 74.99 = ?
