Answer 1

Correct Question:

Q: A person sets to cover a distance of 12 km in 45 minutes. If he covers 3/4th of the distance in 2/3rd of time, then what is the speed in the remaining time?

Answer:

• The speed in the remaining time is 12 km/hr.

Step-by-step explanation:

Given that:

• Total distance = 12 km
• Total time = 45 minutes

To Find:

• If he covers 3/4th of the distance in 2/3rd of time, then what is the speed in the remaining time?

Finding the 3/4th of the distance:

• Total distance × 3/4
• 12 km × 3/4
• 9 km

• Remaining distance = 12 km - 9 km
• Remaining distance = 3 km

Finding the 2/3rd of time:

• Total time × 2/3
• 45 minutes × 2/3
• 30 minutes

• Remaining time = (45 - 30) minutes
• Remaining time = 15 minutes

Converting 15 minutes in hours:

• 60 minutes = 1 hour
• 1 minute = 1/60 hours
• 15 minutes = 15/60 = 0.25 hours

Now finding the speed in the remaining time:

Formula: Speed = Distance/Time

• Speed = (3 km) / (0.25 hours)
• Speed = 12 km/hour

Answer 2

Answer:

Appropriate Question :-

Pawan sets to cover a distance of 12 km in 45 minutes. If he covers 3/4th of the distance in 2/3rd of time, then what is the speed in the remaining time?

To Find :-

Speed of remaining time

Solution :-

At first he covers ¾ of 12

Therefore,

¾ × 12 = 9 km

Now,

Remaining distance = 12 - 9

=> 3 km

Now,

When he takes ⅔ of time

45 × ⅔

15 × 2

30 min

Remaining time = 45 - 30

=> 15 minutes

Now,

15 minutes = 15/60 = 3/12 = 1/4 = 0.25 hours

Speed = Distance/Time

Speed = 3/0.25

Speed = 12 hr
