A driver of truck sees an ambulance 160 meters ahead of him. After 20 seconds the ambulance is 140 meters behind. If the speed of the truck is 80 kmp/h, then what is the speed of the ambulance?
Relative speed = (total distance )/(total time) = (160+140)/20 = 15 m/sec Speed in km/hr = 15 × 18/5 = 54 km/hr Relative speed = speed of truck – speed of ambulance 54 = 80 – Speed of ambulance Speed of ambulance = 80 – 54 = 26 km/hr
30.22% of (61.9 × 5.01) + 59.97 =?
499.99 + 1999 ÷ 39.99 × 50.01 = ?
(2310.23 ÷ 32.98) + (1008.32 ÷ 23.9) + 1594.11 = ?
41.98% of 2200.031 + 15% of 3999.9 = ?
(34.03 + 101.98) ÷ 17.211 = 89.9 – 25.23% of ?
? % of 759.96 + 932.99 = 1237.01
24.912% of ? – 35.06% of 199.91 = 19.97% of 224.89
3.992 + (3.01 × 2.98) + ? = 225.03
124% of 620.99 + 11.65% of 1279.23 = ?
? = 26.08 + 18.99 × 25.07
