A bus covers 78km in 40 min how much time it will take to cover a distance of 182km
Answers
Answer:
Formula for constant speed is v=d/t, d=distance, t= time
For the first part of the journey the time taken is:
t = 36/54=2/3 hrs
His total journey should last 1 hours 30 minutes= 3/2 hours
Therefore after the first part of the journey, its time left is
t= (3/2) - (2/3)= 5/6 hours
The remaining distance to travel is
d = 72 – 36 = 36km
The bus should then travel at a speed of
v= 36 / (5/6) =43.2 km/hour
hope you understand and thanks for reading

Answer:
Formula for constant speed is v=d/t,
d=distance, t= time
For the first part of the journey the timne
taken is:
t 36/54-2/3 hrs
His total journey should last 1 hours 30
minutes= 3/2 hours
Therefore after the first part of the
journey, its time left is
t (3/2) - (2/3)= 5/6 hours
The remaining distance to travel is
d 72-36 36km
The bus should then travel at a speed of
v= 36/ (5/6) =43.2 km/hour
