Question

Выразите в часах: а) 2 ч 20 мин., 1 ч 30 мин., 3 ч 15 мин, 5 ч 24 мин; б) 90 мин, 250 мин, 180 мин, 165 мин.

Answer 1

1)
2 ч 20 мин = 2 + ( 20/60 ) часа = 2 1/3 часа
1 ч 30 мин = 1.5  часа
3 ч 15 мин = (3 + 15/60 ) часа = 3 1/4 часа
2) 
90 мин = 90/60 часа = 3/2 = 1.5 часа
250 мин = 250/60 = 25/6 = 4 1/6 часа
180 мин = 180/60 = 3 часа
165 мин = 165/60 = 2.75 часа

Answer 2

Conversion of Time to Hours

a) For the given times: - 2 hours 20 minutes - 1 hour 30 minutes - 3 hours 15 minutes - 5 hours 24 minutes

The conversion to hours is as follows: - 2 hours 20 minutes = 2.33 hours - 1 hour 30 minutes = 1.5 hours - 3 hours 15 minutes = 3.25 hours - 5 hours 24 minutes = 5.4 hours.

b) For the given times: - 90 minutes - 250 minutes - 180 minutes - 165 minutes

The conversion to hours is as follows: - 90 minutes = 1.5 hours - 250 minutes = 4.17 hours - 180 minutes = 3 hours - 165 minutes = 2.75 hours.

Therefore, the conversions in hours are as listed above.
