1 answer:

8 0

37. 3/8 hours

You can get this by dividing 3/4 by 2.

The key to doing these types of problems is remembering that if they are going faster by that much, it doesn't matter what the speeds are. You can treat it as if one is standing still and the other is going 2mph.

The ratio of boys to girls in a group is 2:1. If there are 18 more boys than girls, work out how many girls there are.

rusak2 [61]

Hey there! I’m happy to help!

Let’s use the variable g to represent the girls. This ratio shows that there are twice as many boys as girls (boys=2g)We also see that there are 18 more boys that girls. Let’s set up an equation

g+18=2g
We subtract 18 from both sides
g=2g-18
We subtract 2g from both sides.
-g=-18
We divide both sides by -1
g=18

Therefore, there are eighteen girls.

I hope that this helps! Have a wonderful day!
