Question

Two cars are moving in the same direction with the same speed 30 km/h. they are separated by a distance of 4km. What is the speed of the car moving in theopposite directions if it meets these two cars at an interval of 5 minutes?

PLS I NEED THE CORRECT ANSWER PLEASEEE CORRECT ANSWER GETS BRAINLIEST

Answer 1

Answer:

what is the speed of the second car

Answer 2

This is a question related to relative motion,

here is the answer :-

let the two cars moving in same direction be A and B and the third car be C.

let the velocity of C be 'u'.

so velocity of C with respect to B would be.

u+30(as they are moving in opposite directions).

+30(as they are moving in opposite directions).do the speed u+30 would be given by

+30(as they are moving in opposite directions).do the speed u+30 would be given by5/(4÷60) = u+30

+30(as they are moving in opposite directions).do the speed u+30 would be given by5/(4÷60) = u+305×60/4= u+30

+30(as they are moving in opposite directions).do the speed u+30 would be given by5/(4÷60) = u+305×60/4= u+3075 = u+30

hence ,u = 45 kmph
