Question

Aditya walks 18 km in 4 hours and diya walks 11 km in 2 hours. Find the ratio of the speeds.

Answer 1

Answer:

Ratio of Speed = 9 : 11

Step-by-step explanation:

Distance Walked by Aditya is 18 KM in 4 hours

Therefore speedof Aditya= 18KM/4 Hours = 9/2 KM/Hour

Distance Walked by Diya is 11 KM in 2 hours

Therefore Speed of Diya = 11/2 KM/Hour

Ratio of the speed = 9/2 : 11/2

As the denominator is same we can write the ratio of the speed as

9 : 11

Answer 2

ADITYA

Distance = 18 km

Time = 4 hr

As we know,

$Speed = \dfrac{Distance}{Time}$

Solution:-

$Speed= \dfrac{18}{4}$

Both are divisible by 2.

(9×2=18)

(2×2=4)

$Speed= \dfrac{9}{2}$

$Speed= 4.5km/hr$

Divya

Distance = 11 km

Time = 2 hr

As we know,

$Speed = \dfrac{Distance}{Time}$

Solution:-

$Speed= \dfrac{11}{2}$

$Speed= 5.5km/hr$

To Find:-

Ratio of the speeds.

Aditya's speed : Divya's speed

$\dfrac{9}{2}: \dfrac{11}{2}$

Cancel the denominators as they are common.

Ratio of their speeds =} 9:11
