Respuesta :
D. 3 hours
av velocity= total distance travelled÷total time taken
60mph=180m÷x hr
x= 180/60=3hr
av velocity= total distance travelled÷total time taken
60mph=180m÷x hr
x= 180/60=3hr
By definition of speed:
Speed = Distance / Time
So, Time = Distance / Speed = 180 / 60 = 3 hours
Answer is D
Speed = Distance / Time
So, Time = Distance / Speed = 180 / 60 = 3 hours
Answer is D
