## Rajasthan Board RBSE Class 5 Maths Chapter 11 Time Ex 11.1

Question 1.

**Convert the time units of following questions,**

(i) \(10\frac { 3 }{ 5 }\) hour = …………… minute

(ii) \(2\frac { 1 }{ 4 }\) hour = …………… seconds

(iii) \(\frac { 1 }{ 5 }\) minute = …………… seconds

(iv) \(1\frac { 2 }{ 3 }\) minute = …………… seconds

Solution.

(i) \(10\frac { 3 }{ 5 }\) hour = 10 hour + \(\frac { 3 }{ 5 }\) hour

= 10 x 60 minutes + \(\frac { 3 }{ 5 }\) x 60 minutes

= 600 minutes + 3 x 12 minutes

= 600 minutes + 36 minutes

= 636 minutes

(ii) \(2\frac { 1 }{ 4 }\) hour = 2 hour + \(\frac { 1 }{ 4 }\) hour

= 2 x 60 minutes + \(\frac { 1 }{ 4 }\) x 60 minutes

= 120 minutes + 15 minute

= 120 x 60 seconds + 15 x 60 seconds

= 7200 seconds + 900 seconds

= 8100 seconds

(iii) \(\frac { 1 }{ 5 }\) minute = \(\frac { 1 }{ 5 }\) x 60 seconds = 12 seconds

(iv) \(1\frac { 2 }{ 3 }\) minute = 1 + \(\frac { 2 }{ 3 }\) minute

= 1 x 60 seconds + \(\frac { 2 }{ 3 }\) x 60 seconds

= 60 seconds + 2 x 20 seconds

= 60 seconds + 40 seconds

= 100 seconds
