Question

Maria rode her bicycle 5 3/4 miles in 3/4 hour. What is her average speed in miles per hour?

Answer 1

To find the speed you use the distance formula. d=rt.
5.75=.75s
s=7 2/3
7 2/3 miles per hour
Hope this helps :)

Answer 2

so miles per hour
self explanatory
speed is miles per hour
miles divided by hours
per hour means per 1 hour so
miles per 1 hour
so therefor we convert it to a fraction and make the bottom equal to 1
convert 5 and 3/4 to improper fracitons fors
5 and 3/4=20/4+3/4=23/4
so we have


`( (23)/(4) )/( (3)/(4) )`
to convert the bottom number to one, we take it individually
3/4 times what=1
multiply both sides by 4/3
12/12 times what=4/3
1 times what=4/3
what=4/3

answe ris 4/3

to make the fraction equivilent, we must multiply the whole fraction (
`( (23)/(4) )/( (3)/(4) )`) by 1 or x/x or
`( (4)/(3) )/( (4)/(3) )`
so


`( (23)/(4) )/( (3)/(4) )` times
`( (4)/(3) )/( (4)/(3) )` =
`( (92)/(12) )/( (12)/(12) )` =
`( (92)/(12) )/(1 )` =
`( 92)/( 12)` =
`( 46)/( 6)`=
`( 23)/( 3)`=7 and 2/3
answer is 7 and 2/3 miles per hour
