the arrivals of the buses at town Q now will be​

Answer 1

Answer:

25 sec

Explanation:

Given interval= 20s

Speed= 50km/h

We know Speed= distance/time

hence distance will be

distance= speed×time

distance= 50×20= 1000km

Now as the speed is reduced to 40km/h

therefore time interval will be= distance/speed= 1000/40= 25sec
