Minus 150 meters pepega I don’t quite understand the question but that is one way to get from 400 to 350 meters.
Dividing 1.93km by 23 minutes, you get 0.083 km per minute, or 5.03 km per hour
X+y = 4, therefore y = 4-x when you rearrange the equation.
You can subsitute this in: x-(4-x) = 6
-4+x = 6-x
x=10-x
2x = 10
x = 5
Substitute x into the previous equation:
5+y = 4
y = 4-5
y = -1
Go to the number next to the one you cannot subtract from, take one away, and add a one in front of the number you cannot subtract from. e.g.
27 1(1)7 the answer would be 9
-8 -8
for your problem the answer would be 1109
The partial peoduct is 301.
