65 time 2
then divide 65 by two as your half
then 32.5 plus 130
which is 162.5 miles
The solution can be obtained as follows:
We are given the speed of the ship as 20 km/h
Time taken by ship to travel is 4h.
We will apply speed distance formula here given by:
So here we will plug in the given values to find the distance covered by the ship:
Distance = 80 km
Answer: The distance traveled by the ship is 80 km.
Answer: 36 and 28
x + x+2 = 74
2x = 72
x1 = 36
x2 = 28
The proportion that Alan solved was
x/200 = 8/25
His working as shown was
(8)(x) = (25) (200)
8x = 5000
He divided both sides of the equation by 8. It became
8x/8 = 5000/8
x = 625
The correct steps are
25x = 200 × 8 = 1600
Dividing both sides of the equation by 25, it becomes
x = 1600/25
x = 64
Alan's error were:
1) He got the wrong product when he multiplied 25 by 200.
2)He got the wrong quotient when he divided 5,000 by 8.
