Ответ:
To cover 1320 miles they will need 12 hours of time.
Step-by-step explanation:
Given information:
The cars are moving in opposite direction and the starting point of the cars are same:
The speed of first car![=50 mph](/tpl/images/0488/4973/a7fd7.png)
The speed of second car![=60mph](/tpl/images/0488/4973/bd803.png)
As we know, Distance = Speed
Time
If the first car covered the distance![d](/tpl/images/0488/4973/17a1d.png)
Then the distance covered by second car will be![1320-d](/tpl/images/0488/4973/0398e.png)
Now form two equation taking time as
from the given information and equate them.
And![1320-d=60 \times t](/tpl/images/0488/4973/c05bc.png)
On solving the above equation:
Hence, to cover 1320 miles they will need 12 hours of time.

A B
50 mph 60 mph
so let's recall that d = rt, distance = rate * time.
both cars start out at the same time, say "t" hours.
after "t" hours car A has covered say "d" miles, since there's a total of 1320, then car B must surely had covered the slack, or 1320 - d.
