Question

A distance covered by three cars is in ratio of
1:2:3. if ratio of time of journey is 3:2:1 then
find ratio of their speed ?​

Answer 1

Answer:

1 : 3 : 9

Step-by-step explanation:

D1= 1; D2 = 2; D3 = 3

T1 = 3; T2 = 2; T3= 1

Distance (D) = Speed (S) × Time(T)

S = (D÷T)

S1 = D1/T1 = 1/3

S2 = D2/T2 = 2/2

S3 = D3/T3 = 3/1

Ratio of S1:S2:S3 = 1/3 :2/2 : 3/1

= 1/3 : 1 : 3

LCM of denominators 3,1,1 = 3

S1 = (1/3)×3 = 1

S2 = 1 × 3 = 3

S3 = 3 × 3 =9

So, the ratio of their Speed = 1 : 3 : 9

Answer 2

Hᴇʀᴇ's Yᴏᴜʀ Aɴsᴡᴇʀ:-

Rᴇǫᴜɪʀᴇᴅ Rᴀᴛɪᴏ:- 1/3, 2/2, 3/1

= 1/3 : 1 : 3

= 1/3 × 3 : 1 × 3 : 3 × 3

[ . ° . Sᴘᴇᴇᴅ = Dɪsᴛᴀɴᴄᴇ/Tɪᴍᴇ ]

= 1 : 3 : 9
