A train had to travel the distance from A to B at an average speed of 56 km/h. After a 1.5-hour journey from station A, the train stopped for 30 minutes. To reach station B on schedule, it had to travel the remaining distance at an average speed of 63 km/h. Calculate the distance between cities A and B.

Final Answer:

s =  336 km

Step-by-step explanation:

v1=56 km/h t1=1.5 h t2=30 min h=30:60  h=0.5 h v2=63 km/h  s1=v1 t1=56 1.5=84 km s= v1 t t3 = s2/v2  v2 = tt1t2ss1 v2 = s/v1t1t2ss1  v2 (s/v1t1t2)=(ss1) 63 (s/561.50.5)=(s84)  7s=2352  s=72352=336  s=336   Verifying Solution:  s2=ss1=33684=252 km t=s/v1=336/56=6 h t3=s2/v2=252/63=4 h  x=tt1t2t3=61.50.54=0 h
