Question
A driver of an army truck sees an ambulance 80 meters
ahead of him. After 10 seconds the ambulance is 70 m behind. If the speed of the truck is 104kmph, then what is the speed of the ambulance?Solution
Relative speed = (Total Distance)/(Total Time) = (70 + 80)/10 = 15 m/sec Speed in km/hr = 15 x 18/5 = 54 km/hr Relative speed = speed of truck – speed of ambulance 54 = 104 – speed of ambulance Speed of ambulance = 104 – 54 = 50km/hr
