Set up a ratio:
You drove 72 minutes and 100 km = 72/100
You want the number of minutes (x) to drive 150 km = x/150
Set the ratios to equal each other and solve for x:
72/100 = x/150
Cross multiply:
(72 * 150) = 100 * x)
Simplify:
10,800/100x
Divide both sides by 100:
x = 10800/100 = 108
This means it would take 108 minutes to drive 150 km.
Now subtract the time you have already driven to fin how much more you need:
180 - 72 = 36 more minutes.
It is the first one because if u gain an amount and lose that same amount you don't gain anything.
25-25=0
To solve this, set up a proportion. 72/21.6=110/x Cross multiply. 72x=2376. Solve x=33
The answer would be c. it is a flat Sudanese so you only need to square it
