Question

A toy train A covers 50 m in a minute, While toy train B covers 1.35 Km in half an hour. What is the ratio of the speeds of the two toys train?

Answer 1

Answer:

Ratio of the speeds of the two toys train = 10 : 9

Step-by-step explanation:

Given: There are two toys train A and B,

A covers 50 m in a minute.

B covers 1.35 km (1350 m) in half an hour (30 minutes).

Formula: Speed = Distance / Time

Ratio of the speeds of the two toys train:

Speed of A : Speed of B

50/1 : 1350/30

50 : 45

10 : 9

Answer 2

$\: \: \: \: \: \:{\Large{\bf{\underbrace{Required \: answer}}}}$

${\large{\bold{\rm{\underline{Given \: that}}}}}$

◕ Toy train A covers 50 m in a minute

◕ Toy train B covers 1.35 km in half an hour.

${\large{\bold{\rm{\underline{To \; find}}}}}$

◕ The ratio of the speeds of the two toys train.

${\large{\bold{\rm{\underline{Solution}}}}}$

◕ The ratio of the speeds of the two toys train = 10:9

${\large{\bold{\rm{\underline{Using \: concepts}}}}}$

◕ Converting km into m

◕ Formula to find speed

${\large{\bold{\rm{\underline{Using \: formulas}}}}}$

◕ Converting km into m

➝ 1 km = 1000 m

◕ Formula to find speed

➝ Speed = Distance / Time

${\large{\bold{\rm{\underline{Full \: Solution}}}}}$

☀ Let us convert km into m firstly,

⇥ 1 km = 1000 m

⇥ 1.35 × 1000 m

⇥ 1350 metres.

☀ Now let us find the speed ratio

⇥ Speed = Distance / Time

But we have to find ratio so,

⇥ Speed of train A : Speed of train B

⇥ 50/1 : 1350/30

⇥ 50 : 135/3

⇥ 50 : 45

⇥ 10 : 9

${\pink{\frak{Henceforth, \: 10:9 \: is \: speed \: ratio}}}$
