Question

Maria normally walks 3/4 of an hour each day.Today she walked 5/2 times as long as normal. Did maria walk for more than 5/2 hours?

Answer 1

Answer:

Marie did not walk  $\dfrac{5}{2}$ hours more, but she walk $\dfrac{9}{8}$ hours more .

Step-by-step explanation:

Given as :

The normal hours did Maria walks each day = $\dfrac{3}{4}$ hours

The hours did Maris walk today = $\dfrac{5}{2}$ times normal hours walk

Or, The hours did Maris walk today = $\dfrac{5}{2}$ ×  $\dfrac{3}{4}$ hours

Or, The hours did Maris walk today = $\dfrac{5\times 3}{2\times 4}$ hours

Or, The hours did Maris walk today =  $\dfrac{15}{8}$ hours

Now, Let The difference between normal hours walk and today hours walk = x hours

So, x = $\dfrac{15}{8}$ hours -  $\dfrac{3}{4}$ hours

Taking LCM

Or, x = $\dfrac{15 - 6}{8}$ hours

Or, x =  $\dfrac{9}{8}$ hours

So, Maria walk $\dfrac{9}{8}$ hours more

Hence, Marie did not walk  $\dfrac{5}{2}$ hours more, but she walk $\dfrac{9}{8}$ hours more . Answer
