A bus covers 100 km in first 2 hours , 64 km in the next 1 hour and 72 km in the next 2 hour . Find the average speed of the bus during the whole journey
Answers
Step-by-step explanation:
For first 2hrs it goes 100km .
For Next 1hr(3rd hr) it goes 64km.
And in Next 2hrs it travels 72km.
Total distance travelled = 100+64+72
= 236km
Total time taken to travel = 5hrs
• Speed = Distance/time
S = 236/5
= 47.2km/hr
(OR)
Km/hr should be converted into metres/second.
1km ×5/18 is the constant term to covert km/hr to m/s
100km ×5/18 = 27.7m/s
64km ×5/18 = 17.7m/s
72km×5/18 = 20m/s
Now, totalling distance.
27.7+17.7+20 = 65.4m/s
Total time = 5hrs
Speed = Distance/time
S = 65.4/5
S = 13.08 m/s.
The Average speed = 13.08 m/s or 47.2km/hr
Answer:
add d distance and add d time
