Answer:
2 hrs
Step-by-step explanation:
Boat moving rate= 11 mph
river's current flow rate= 3 mph
By adding both of them, we get
11 + 3 mph=14 mph
Now,
Time taken= distance travelled/ velocity
= 27/14
= 2 hrs

Step-by-step explanation:
Remark
Let the shorter base = x
Let the longer base = 3x
h = 5
Area = 60
Formula
Area = (b1 + b2)*h /2
Solution
60 = (x + 3x)*5 / 2 Multiply both sides by 2
2*60 = (x + 3x)*5 Combine like terms
120 = 4x *5
120 = 20x Divide by 20
120/20 = x
x = 6
Therefore the two bases are
x = 6
3x = 18
