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

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
