Question

two buses start from the same bus stand. at 8 am one travels at 40 km/h and the other at 50km/h. the second bus reaches the next stop at 10a.m .how much later will the first bus arrive?

Answer 1

Distance = speed*time
D=50*2 (10-8)
D=100km

time=distance/speed
T=100/40
T=2.5hrs= 2hr and 30 mins

the first will take 30mins more to reach the stop

Answer 2

Answer:

8−9=4x+2x

−1=6x

−1/6=x
