Step-by-step explanation:

Manoj rode in 50 min = 24km

Manoj rode in 1 min = changing km into m

24×1000

2400÷50

48m

Manoj will ride 36 km in = changing km into m

36×1000

3600÷48

75min

Answer 2

Answer:

• Time taken by Manoj to cover 36 km is 75 minutes.

Step-by-step explanation:

Given that:

• Manoj rode 24 km in 50 minutes.

To Find:

• Time taken by Monoj to ride 36 km.

Solution:

Converting distance into m:

As,

• 1 km = 1000 km

Therefore,

24 km = 24 × 1000 = 24000 m

As we know that:

• Speed = Distance/Time

Here,

• Distance = 24000 m
• Time = 50 minutes

Substituting the values,

$\sf{Speed=\dfrac{24000}{50}\;m/min}$

$\sf{=\dfrac{2400\!\!\!\not{0}}{5\!\!\!\not{0}}\;m/min}$

$\sf{=\dfrac{2400}{5}\;m/min}$

$\sf{=480\;m/min}$

Hence,

• Speed = 480 m/min.

Converting 36 km to m:

• 1 km = 1000 m

• 36 km = 36 × 1000 = 36000 m

Now, as we know that:

• Time = Distance/Speed

Substituting the values,

$\sf{Time=\dfrac{36000}{480}\;min}$

$\sf{=\dfrac{3600\!\!\!\not{0}}{48\!\!\!\not{0}}\;min}$

$\sf{=\dfrac{3600}{48}\;min}$

$\sf{=75\;min}$

Hence,

• Time taken to cover 36 km = 75 min
