Answer:
15 hours
Hello. I hope this helps.
Step-by-step explanation:
As they move towards each other:
- one travels 38 km per hour
- the other travels 22 km per hour
=>
- the distance between them decreases 38 + 22 = 60 km per hou
The distance between them is 900 km at the start. We want to know when the distance becomes 0 km.
Time = distance / speed
= 900 km / 60 km/hr
= 15 hr
