a train travels 60 km/hr for 0.52 hour, 30 km/hr for next 0.24 hr and
then 70 km/hr for next 0.71hr
what is the average speed for the trip?
:
Find the total distance of the trip; (dist = speed * time)
d = (60*.52) + (30*.24) + (70*.71)
d = 31.2 + 7.2 + 49.7
d = 88.1 km
:
Find the total time for the trip
t = .52 + .24 + .71
t = 1.47 hrs
:
Find the av speed (a = d/t)
a =
a = 59.932 ~ 60 km/hr av speed for the trip
then 70 km/hr for next 0.71hr
