Ответ:
The ships will pass after 34.57 hours
Step-by-step explanation:
Given,
Speed of ship A = 17.4 miles per hour
Distance covered by ship A in two hours = Speed * Time = 17.4 * 2 = 34.8 miles
Let,
t be the time.
Distance traveled by ship A = 17.4t + 34.8
Speed of ship B = 21.8 miles per hour
Distance covered by ship B = 34.8t
Distance of Red Sea = 1390 miles
Now;
Distance of ship A + Distance of ship B = 1390
Dividing both sides by 39.2
The ships will pass after 34.57 hours
