first bus travel 36 kilometre in in 30 minutes and second bus travel 120 kilometre 2 h o u r s which bus travel fast
Answers
Answer:
First Bus Travels Fast than the 2nd bus
Difference is 72km/h- 60km/h = 12km/h
Speed of Ist Bus = 72 km/h
Speed of 2nd Bus = 60km/h
Explanation:
Distance Traveled by Ist bus = 36km
Time taken = 30 minutes
Speed = D/T = 36km ÷ 30 minutes
( convert time into hours)
= 1 hrs = 60 minutes
( convert distance into metres)
( convert time into seconds)
= 1 Km = 1000m
36 Km = 36×1000m
= 36000 m
= 1 min = 60 s
30 min = 30×60s
= 1800 s
Speed = 36000m/1800s
= 20m/s
Distance traveled by the 2nd bus = 120 km
Time taken = 2 hours
Speed = D/T
= 120km/2hrs
= 60km/hr
Difference between the speeds of bus
= Ist bus = 20m/s
1 m/s = 18/5 km/h
= 20 × 18/5 km/h
( solve the equation)
= 4×18 km/h
= 72 km/h
= 2nd bus = 60 km/h
Therefore, Ist bus travels fast than the 2nd bus.
