Question

Answer both 2 and 3 please

Answer 1

Time units.

2.

1 day = 24h

1h = 60min

We have 4h 20min

`4h + 20min = 4h+(20)/(60)h=4h+(1)/(3)h=4(1)/(3)h=(13)/(3)h`

`((13)/(3))/(24)=(13)/(3)\cdot(1)/(24)\\\\\huge\boxed{(D)\ (13)/(72)}`

3.

6:51PM + 9min → 7:00PM

7:00PM + 27min → 7:27PM

9min + 27min = 36min

`36min=(36)/(60)h=(3)/(5)h`

`\huge\boxed{(C)\ (3)/(5)}`
