Answer 1

Answer:

I think B ) 1hr 15 min

Step-by-step explanation:

Time = ( 45 min )3/4 hour for 60%

therefore time for 100% = 3/4 × 100/60

Answer 2

M S Dhoni requires 1 hour 15 minutes to complete his run. (Option-B)

Given,

By running for 45 minutes, MS. Dhoni has completed 60% of his run.

To find,

Total time required to finish the complete run.

Solution,

We can simply solve this mathematical problem using the following process:

According to the question,

Finishing the complete run means finishing 100% of the run.

Now, by using the unitary method, we get;

MS.Dhoni has completed 60% of his run by running for 45 minutes

=> MS. Dhoni has completed 1% of his run by running for (45/60) minutes

=> MS. Dhoni has completed 100% of his run by running for (45/60 × 100) minutes, that is, 75 minutes

Now, according to the units of conversion;

60 minutes = 1 hour

=> 75 minutes = 60 minutes + 15 minutes

= 1 hour + 15 minutes

Hence, M S Dhoni requires 1 hour 15 minutes to complete his run. (Option-B)
