Hina drives first 120 km in 2 hrs and next 180 km in next 4 hrs. What is her average speed for the entire trip in km per hour?

step by step explanation plz

Given ,

We need to find

Firstly finding speed

• Speed in first 2 hrs = 120/2 = 60km/h

• Speed in next 4 hrs = 180/4 = 45 km/h

As we know that ,

Substituting known values we have ,

⇒ Average speed = 2 ( 60 ) ( 45 ) / 60 + 45

⇒ Average speed = 2(60)(45)/105

⇒ Average speed = 5400/105

⇒ Average speed = 51.42 km/h

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
