Question

If A cover a curtain distance in 30 min and B cover same distance in 45 min.Who travel in higher speed​

Answer 1

Ratio of speed = 3 : 4

Ratio of speed = 3 : 4Ratio of time= 4 : 3

Ratio of speed = 3 : 4Ratio of time= 4 : 34unit−3unit= 1unit= 30min

Ratio of speed = 3 : 4Ratio of time= 4 : 34unit−3unit= 1unit= 30minSo, 4 units = 30×4=120 min

Ratio of speed = 3 : 4Ratio of time= 4 : 34unit−3unit= 1unit= 30minSo, 4 units = 30×4=120 minRequired time = 2 hrs

Answer 2

Step-by-step explanation:

A : B

Ratio of speed = 3 : 4

Ratio of time= 4 : 3

4unit−3unit= 1unit= 30min

So, 4 units = 30×4=120 min

2 hours
