Question 1110738
let speed of one bus be x kmh
the other will be (x+16)   kmh

they are moving in opposite directions
so effective speed  is x+x+16 -> 2x+16

distance = 1270 km
time = 5 hours

d= s x t
1270 = (2x+16) *5
1270/5 = 2x +16
254 = 2x+16
2x= 238
x= 119 km/h
add 16 to get speed of second bus
