Q.5 (a) (ii)
can any1 help me in this??

As the distance traveled by Ben and Ali is same, so firs find Ali's distance at 150s by taking the area of trapezium. Then as Ben moved at a constant speed, the distance traveled by him is area of rectangle with length 150s. So, put Ali's distance, that is, area of trapezium equal to 15 multiplied by X. Where X is Ben's speed.

Area of trapezium = 150 x X

well this is what i did and cudnt get to the ans
btw the report strictly says not to do this

 

[XPF MASTER]

helloww ppl???

 

[Zishi]

What? This is the 100% correct way! And this gives you the answer, as I've solved this question many times. Plus, check your area of trapezium at t=150s. There may be mistake in it.
