Turn hours into minutes
1hr = 60mins
Add the 60mins with 30mins since it’s 1hr and 30 mins. Which will equal 90mins
9miles/ 90minutes
You can simplify
1 mile/ 10 mins
So for 1 mile it takes 10 mins
And the problem is asking how much will it take for her to run 12 miles
Meaning it will take 120 minutes for her to run 12 miles.
300 200
20 30
+ 4 + 1
---------
It’s 18
If they have to be equal, every vase has to have a yellow flower therefore if you had 1 yellow flower and 1 white flower (the lowest possible equal combination) then you can only have 18 groups otherwise you would have an equal number in each case
Use exponential law, we have
You’d have to solve your equations!
they’d be the same when x=-56
and when x=-56 they’d BOTH equal -27
