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?

Sagot :

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

[tex]\text{Speed}=3\text{ }\frac{1}{2}\text{ miles per hour}[/tex][tex]\text{Distance =sp}eed\times time[/tex]

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

[tex]\text{Distance =3}\frac{1}{2}\times\frac{1}{2}\text{ miles}[/tex]

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

[tex]3\frac{1}{2}\times\frac{1}{2}=\frac{3\times2+1}{2}\times\frac{1}{2}[/tex]

[tex]=\frac{7}{2}\times\frac{1}{2}=\frac{7}{4}[/tex]

[tex]=1\frac{3}{4}\text{ miles.}[/tex]

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