Problema Solution
a taxi hurries for 1.8 hours with a constant speed of 113 km/h and then for another 5 hours 40 minutes
with a constant speed of 52 km/h what is its average speed
Answer provided by our tutors
5 hr 40 min = 5 + 40/60 = 5 + 2/3 = 17/3
The average speed equals the total distance traveled divided by the total time:
v = (1.8*113 + (17/3)*52)/(1/8 + 17/3) = 86 km/h
The average speed is 86 km/h.
