speed = (distance/time) distance = speed time = 10 × 42 = 420 km to cover the same distance in 7 hours speed = 420/7 = 60 Km/h increase in speed = 60 -42 =18 km/h

...? = (7.11/2.12) + (10.88/4.09) + (45.12/11.98)
(239.89 ÷ 3.89) – (144.01 ÷ 5.73) = ?2
2660.03 ÷ 69.98 x 49.9 = ? + 10.32
If 'a' = √1024 ÷ 4 + 96 ÷ 3 + 85 ÷ 17 and 'b' = 30 × 18 ÷ 6 - 7² + 110, then find the value of (a + b).
...233.98 + 73 × √35.95 - ? = 275.94 ÷ 3.99
? = 22.08 + 13.99 × 22.07
? × 32.91 – 847.95 ÷ √16.4 – 13.982 = √24.7 × 24.04
30.05% of 360.05 – 25.15% of 99.99 × 3.02 = ?
