Tanker A due East 15 km/h
Tanker B due West 29 km/h
Distance 900 miles
Let time they meet be x hours
Tanker A due East distance traveled 15 x miles
Tanker B due West distance traveled 16 x miles

Time taken to meet is same
t=d/r
combined speed= 44 mph

44 x = 900
x= 20.45 hours
Tanker A due East 15x=306.82 miles from Corpus Christi
