Question

Hi are you a tutor for the HESI exam for nursing Maria can walk 3 1/2 miles in one hour. At this time how far can Maria walk in 1/2 hour?

Answer 1

Given that Maria can walk 3 1/2 miles in one hour.

`\text{Speed}=3\text{ }(1)/(2)\text{ miles per hour}`
`\text{Distance =sp}eed* time`

The distance that Maria can walk in 1/2 hour is

`\text{Distance =3}(1)/(2)*(1)/(2)\text{ miles}`

Multiply the 3 1/2 miles by 1/2 to compute the distance covered in 1/2 hour.

`3(1)/(2)*(1)/(2)=(3*2+1)/(2)*(1)/(2)`

`=(7)/(2)*(1)/(2)=(7)/(4)`

`=1(3)/(4)\text{ miles.}`

Maria can walk 1 3/4 miles in 1/ 2 hour.
