d = 36 km
t = 40 min = 2/3 hr
s = d/t = 36×3/2 = 54 km/h
Case 1
t = 8 hr
s = 54 km/h
d = s×t = 54×8 = 432 km
Case 2
d = 162 km
s = 54 km/h
t = d/s = 162/54 = 3 hr
t = 40 min = 2/3 hr
s = d/t = 36×3/2 = 54 km/h
Case 1
t = 8 hr
s = 54 km/h
d = s×t = 54×8 = 432 km
Case 2
d = 162 km
s = 54 km/h
t = d/s = 162/54 = 3 hr
