Question

A man travels $\bf6 \frac{1}{4}$ km in 1 hour. How many kilometres does he travel in $\bf6 \frac{1}{2}$ hours ?

Answer 1

Answer:

$\bf{40\frac{5}{8}hours}$

Step-by-step explanation:

First of all :

6 + 1/4

= ( 4 × 6 + 1 )/4

= ( 24 + 1 )/4

= 25/4

The man travels 25/4 km in 1 hour .

6 + 1/2

= ( 6 × 2 + 1 )/2

= ( 12 + 1 )/2

= 13/2

The man travels 25/4 km in 1 hour

The man in 13/2 hours will travel :  

25/4 × 13/2

⇒ ( 25 × 13 ) / ( 4 × 2 )

⇒ ( 325 ) / ( 8 )

⇒ $\bf{40\frac{5}{8}$
