b) : 1 mile will be traveled.

Explanation:

a)

`{ \tt{ \blue{0.5 \: \: miles }\: \: are \: travelled \: \: in \: \: { \green{0.5 \: hours}}}} \\ { \tt{ \blue{5.2 \: miles}{ \: \: will \: \:be \: \: travelled \: \: in \: \: { \green{( (5.2 * 0.5)/(0.5)) \: hours }}}}} \\ \\ { \underline{ \: = { \tt{\: 5.2 \: hours \: \: or \: \: 5 (1)/(5) \: hours }}}}`

b)

`{ \tt{ \green{0.5 \: hours} \: \: are \: \: taken \: \: to \: \: travel \: \:{ \blue{ 0.5 \: \: miles}}}} \\ { \tt{ \green{1 \: hour}{ \: \: will \: \: be \: \: taken \: \: to \: \:travel \: \:{ \green{ ( (1 * 0.5)/(0.5) ) \: miles}}}}} \\ \\ { \underline{ \tt{ \: = \: 1 \: mile}}}`

Answer 2

a. 5.2 hours

b. 1 mile

Explanation:

a. If Jane walked 5.2 miles, how long did her walk take?

Solution:

Since Jane walks 1/2 mile each 1/2 hour.

It means

Jane walks 0.5 mile in 30minutes

let's find first for 1 mile

0.5*2 mile =30*2=60 minutes

1 mile = 1 hour

Now,

5.2 miles =5.2 hours

b. If Jane walked for 1 hours, how far did she walk?

If Jane walked for 1 hours,

then she walked 1/2* 2 =1 miles.
