A taxi hurries for 1 hour 3 minutes wit a constant speed of 118km/hr and then for another 1 hour 9 minutes with a constant speed of 40km/hr. What is its average speed for the total trip?

d = V1*T1 + V2*T2 = 118*1.05 + 40*1.15 =

169.9 km.

Vavg = d/(T1+T2) = 169.9/2.20 = 77.2 km/h.

77.2

To find the average speed for the total trip, you need to calculate the total distance traveled and the total time taken.

1. Calculate the distance traveled during the first part of the trip (speed * time):
Distance 1 = Speed 1 * Time 1
= 118 km/hr * (1 hour + 3 minutes converted to hours)
= 118 km/hr * (1 + 3/60) hours
= 118 km/hr * (1.05) hours
= 123.9 km

2. Calculate the distance traveled during the second part of the trip:
Distance 2 = Speed 2 * Time 2
= 40 km/hr * (1 hour + 9 minutes converted to hours)
= 40 km/hr * (1 + 9/60) hours
= 40 km/hr * (1.15) hours
= 46 km

3. Calculate the total distance traveled:
Total Distance = Distance 1 + Distance 2
= 123.9 km + 46 km
= 169.9 km

4. Calculate the total time taken for the trip (in hours):
Total Time = Time 1 + Time 2
= (1 hour + 3 minutes converted to hours) + (1 hour + 9 minutes converted to hours)
= (1 + 3/60) hours + (1 + 9/60) hours
= 1.05 hours + 1.15 hours
= 2.2 hours

5. Finally, calculate the average speed for the total trip:
Average Speed = Total Distance / Total Time
= 169.9 km / 2.2 hours
≈ 77.23 km/hr

Therefore, the average speed for the total trip is approximately 77.23 km/hr.
