Step-by-step explanation:
the domain is the interval or set of valid values for x.
the range is the interval or set of valid values for y.
the graphic shows no limits of any form and in any direction.
so, x and y cover all values from -infinity to +infinity.
domain = (-infinity, +infinity)
range = (-infinity, +infinity)
please consider the round brackets, as infinity is not a value, and it has therefore to be excluded in the interval definitions.

Answer:
we get 180 minutes; this is equivalent to 3 hours
Step-by-step explanation:
Solving this problem is easier if we convert 2 hr 30 min to min: 150 min.
In the ratio 6:5, the 5 represents the 150 min and we need to determine how long the time interval will be if increased in this ratio.
We write and solve an equation of ratios:
6 x
--- = ------ This becomes 5x = 900 through cross multiplication.
5 150
solving this for x, we get 180 minutes; this is equivalent to 3 hours.
