Answer:
150
Step-by-step explanation:
The are is the sum of are of square and area of triangle.
A=A1+A2
A1=a*a=10*10=100
A2=a*h/2=10*10/2=50
A=100+50=150
Answer: it will take them 4 hours to be 640 kilometers apart.
Step-by-step explanation:
Let t represent the time it will take for both trains to be 640 kilometers apart. It means that the total distance that both trains will covered in t hours is 640 kilometers.
Distance = speed × time
A train leaves Little Rock Arkansas and travels north at 75 kilometers per hour. Distance covered after t hours would be 75 × t = 75t
Another train leaves at the same time and travels south at 85 kilometers per hour. Distance covered after t hours would be 85 × t = 85t
Since the total distance covered is 640 kilometers, then
75t + 85t = 640
160t = 649
t = 640/160
t = 4 hours
Simplify the fractions 7/8 and 2/3 find the common denominatior which would be 24. so 2 times 8 = 16 and 7 times 3 = 21 so 3 16/24 and 5 21/24 is 8 24/24 which would be 9
The answer is 9
