Question

Megha cycle to her school at an average speed of 12 kilometre hours it takes 20 minutes to reach the school if she wants to reach school in 15 minutes what would be speed in metre seconds​

Answer 1

Answer:

She should travel in 4.44 m/s

Step-by-step explanation:

Speed = 12 km/h = 12 * 5/18 m/s = 10/3 m/s

Time taking = 20 minutes = 20*60 seconds = 1200 seconds

So, Distance to school = Speed * Distance = 10/3 * 1200 = 4000 m

Now, She needs to reach school in 15 minutes = 15*60 = 900 seconds

Speed she should travel = 4000/900 = 40/9 m/s = 4.44 m/s
