A 25% Part (d) What is the average speed for the whole trip in meters per second? Au coment o 2017 Dapert TA.ucExplanation / Answer
here,
D1 = 49 miles and t1 = 1.1 hours
D2 = 136 miles and t2 = 2.1 hours
a)
the average speed of the car during first leg , v1 = D1 /t1 = 44.5 miles/hr
b)
the average speed of the car in seccond leg , v2 = D2 /t1 = 64.8 miles/hr
c)
the average speed for the whole trip , v = ( D1 + D2) /( t1 + t2)
v = ( 49 + 136 )/( 2.1 + 1.1)
v = 57.8 miles/hr
d)
the average speed , v = 57.8 miles/hr
v = 57.8 * 0.447 m/s
v = 25.8 m/s
