During the first 18 min of a 60 min trip, a car has an average speed of 11 ms^-1. What should be the average speed for remaining 42 min so that car is having an average speed of 21 ms^-1 for the entire trip?

Answer:
25.3m/s
Explanation:
This looks to me like a physics question based on the kinematic and mechanic aspect of physics
Like any problem in physics we can solve this in multiple ways
For simplicity I’m gonna assume only the kinematic aspect of physics in this problem
Instead of explaining this I’m gonna directly show u the mathematical representation of this question which I believe will be more helpful
D1 + D2 = D
11 x 18 x 60 + 42 x 60 x v = 60 x 60 x21
V = 25.3 m/s
So based on my knowledge of physics I’m gonna say the answer is 23.3m/s
Please mark as brainliest and feel free to ask for any clarification.
