Answer 1

Answer:

105 minutes

Step-by-step explanation:

1 Hour = 60 minutes

3/4 Hours = 3×60/4 = 45 minutes

1 3/4 Hours = 1 hour + 3/4 hours = 60+45 minutes

Answer 2

Answer:

105 minutes

Step-by-step explanation:

$1 \frac{3}{4} = 1 hour + \frac{3}{4} hour$

1 hour = 60 minutes

$\frac{3}{4} \times 60 = 3 \times 15 = 45 minutes$

$Therefore \ , \ 1 \frac{3}{4} = 60 + 45 = 105\ minutes$
