speed of car is 2/3 rd of speed of train if train covered 1100 metres in 33 seconds then find the time in which are covered 270 kilometres
Answers
Answer:
Step-by-step explanation:
Since train covered 1100 metres in 33 seconds so
Train speed = 1100/33 m/s
= 100/3 m/s × 18/5 ( Here 18/5 is multiplied to convert into km/hr )
= 120 km/hr
Car speed = 2/3 × 120 = 80 km/hr
Then time in which car covered 270 km distance = 270/80
= 27/8 hrs
Time in which train covered 270 km distance = 270/120
= 9/4 hrs
if Speed of Car is 2/3rd Of Train speed which covers 1100m in 33 secs then Car would cover 270 km in 3 hrs 22 mins 30 sec
Step-by-step explanation:
Train Covers 1100 m in 33 Secs
Speed = Distance / Time
Speed of Train = 1100/33 m/s
=> Speed of Train = 100/3 m/s
Speed of car = 2/3 of Speed of Train
=> Speed of Car = (2/3) * 100/3
=> Speed of Car = 200/9 m/s
1 m = 1 km/1000
1 sec = 1 hr / 3600
=> Speed of Car = (200/9) * 3600/1000 km/hr
= 400/5 km/hr
= 80 km/hr
Time Taken by Car to Cover 270 km = 270/80 = 27/8 hrs
= 3 hrs 22 mins 30 sec
