Time taken to manufacture one car is 2hr 10min 30sec

= 130min 30 sec

= 7830 sec

Manufacturing 25 cars = 25×7830

= 195750 sec

= 3262 min 30 sec

= 54 he 36 min 30 sec

Answer 2

It will take 58.5416 hours to make 25 cars

Step-by-step explanation:

Time taken to make 1 car  = 2 hour 20 minutes 30 seconds

60 minutes = 1 hour

$1 minute = \frac{1}{60} hour$

$20 minutes = \frac{1}{60} \times 20 = \frac{20}{60}$

3600 seconds = 1 hour

$1 second = \frac{1}{3600}$

$30 seconds = \frac{30}{3600}=\frac{1}{120}$

So, Time taken to make 1 car  = $2 hour + \frac{20}{60} hour + \frac{1}{120} hour=\frac{281}{120} hour$

Time taken to make 25 cars  =$\frac{281}{120} \times 25 = 58.5416 hours$

Hence it will take 58.5416 hours to make 25 cars
