Translate into an algebraic expression and simplify if possible: How far have i travelled if i biked at 10mph for h hrs, i walked 3mph for twice as long as i biked, and ran at 10 mph for one quarter as long as i walked?
(Please help ASAP)

21h miles

Step-by-step explanation:

biking time = h

walking time = 2h

running time = (1/4)(2h) = h/2

total distance = biking distance + walking distance + running distance

= (10)(h) +(3)(2h) +(10)(h/2)

= 10h + 6h + 5h

Total distance equal 21h miles

whole numbers.

step-by-step explanation:

we are given the average monthly rainfall (in millimeters) model r(m) for the years 1900-2009 as a function of the month number m.

as we can see m is taken for the number of months for years 1900-2009.

we know that number of months can't be a negative number or decimal number or a fraction.

so, the number of months could be only positive whole numbers.

therefore, whole numbers is more appropriate for the domain of r.
