Question

Avani travelled 52 km 475 m by bus, 24 km 460 m by car and walked 780 m. How many
kilometres did she travel altogether?

Answer 1

Answer:

• Avani travelled 77.715 km or 77 km 715 m altogether.

Step-by-step explanation:

Given that:

• Avani travelled 52 km 475 m by bus, 24 km 460 m by car and walked 780 m.

To Find:

• How many kilometre did she travel altogether?

Converting the distance in km:

We know that.

• 1000 m = 1 km

By bus,

52 km 475 m = 52 km + 475/1000 km

52 km 475 m = (52 + 0.475) = 52.475 km

By car,

24 km 460 m = 24 km + 460/1000 km

24 km 460 m = (24 + 0.460) = 24.460 km

Walked,

780 m = 780/1000 km

780 m = 0.780 km

Finding the total distance covered by Avani:

Total distance = By bus + By car + Walked

Total distance = (52.475 + 24.460 + 0.780) km

Total distance = 77.715 km

Hence,

• Avani travelled 77.715 km altogether.

Answer 2

Answer:

Question :-

• Avani travelled 52 km 475 m by bus, 24 km 460 m by car and walked 780 m. How many kilometres did she travel altogether.

Given :-

• Avani travelled 52 km 475 m by bus, 24 km 460 m by car and walked 780 m.

Find Out :-

• How many kilometres did she travel altogether.

Solution :-

◘ Let's convert the distance in km :

➻ 52 km 475 m

➻ 52 + $\cancel{\dfrac{475}{1000}}$

➻ 52 + $\dfrac{19}{40}$

➻ $\dfrac{2080 + 19}{40}$

➻ $\dfrac{2099}{40}$

➻ 52.475 km

Again,

➻ 24 km 460 m

➻ 24 + $\cancel{\dfrac{460}{1000}}$

➻ 24 + $\dfrac{23}{50}$

➻ $\dfrac{1200 + 23}{50}$

➻ $\dfrac{1223}{50}$

➻ 24.460 km

And, walked is :

➻ 780 m

➻ $\dfrac{780}{1000}$

➻ 0.780 km

Total distance :

➻ 52.475 + 24.460 + 0.780

➻ 77.715 km

∴ She travel altogether is 77.715 km.
