5/8 = 2/3 the entire box
Half of 2/3 is 1/3, and 2/3 + 1/3 = 1
So find half of 5/8 and add it to 5/8.
5/8 * 1/2 = 5/16
5/8 + 5/16
Change 5/8 to a fraction with a denominator of 16:
10/16 + 5/16 = 15/16
So the original weight is 15/16 pounds.
Answer: the two trains will meet in 2.8 hours
Step-by-step explanation:
Step 1
Speed of train A = 90mph
Speed of train B = 110 mph
Since both trains are travelling towards each other
, their effective speed will be= 90 mph + 110mph= 200mph
Step 2
we know that Speed = distance / time
therefore Time = Distance / speed
Distance = 560 miles
Speed = 200 mph
Time = 560miles / 200mph
2.8 hours
8/8 = 1
1/11 * 1 = 1/11
Hope this helps
