The distance 2

The distance between two ports M and N is 2100km. If two ships travel towards each other with one ship leaving port M at 20km/h and at the same time another ship from port N travel 15km/h.

(I) How long will it take the two ships to meet.
(ii) how far will they be from port M when they meet

Correct answer:

t =  60 h
s1 =  1200 km

Step-by-step explanation:

s=2100 km v1=20 km/h v2=15 km/h  s=v1 t+v2 t  t=v1+v2s=20+152100=60 h
s1=v1 t=20 60=1200 km
