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 bike 54 = 80 – speed of ambulance Speed of ambulance = 80 – 54 = 26km/hr
