Question

A group of friends hike 5 whole 3/4 km, stops for lunch, and then hike another 3 whole 2/5 km. How far did they hike?​

Answer 1

8 19/20 km

Step-by-step explanation:

This is a simple question on addition of fractions.

We analyze the question as follows :

The distance covered in the first part of the journey = 5¾ km

The distance covered in second part of the journey = 3 1/5 km

The total distance covered = distance covered in the first part of the journey + distance covered in the second part of the journey.

Total distance = 5¾ + 3 1/5

We sum the whole numbers first = 3 + 5 = 8

3/4 + 1/5 = 19/20

Total distance = 8 19/20 Km

Answer 2

Answer:

✴ Total distance hiked by them = $\sf\blue {8 \frac{19}{20} km}$ ✴

Step-by-step explanation-

$\sf\green {Given -}$

• Total distance hiked by them in first time= $\sf\red {5 \frac{3}{4} km}$
• Total distance covered by them in second time = $\sf\red {3 \frac{1}{5} km}$

$\sf\green {To \: find-}$

• How far did they hike?

$\sf\green {How \: to \: solve? }$

• As we have given total distance covered by them in 1st and 2nd time. So, to find their total distance, we'll add both distance they travelled in 1st and 2nd time.

$\sf\green {Solution -}$

✴ Total distance = Total distance covered in 1st time + total distance covered in 2nd time. ✴

Total distance = $\sf\red {(5 \frac{3}{4} + 3 \frac{1}{5} )km}$

$\sf\red { = (\frac{23}{4} + \frac{16}{5} )km = \frac{179}{20} km = 8 \frac{19}{20} km}$

So, total distance they hiked =

$\sf\red {8 \frac{19}{20} km}$
