Please help me with this.
katen-ka-za [31]

Answer:

2:45

Step-by-step explanation:

the tiny hand on the clock represents the hour while the long hand on the clock represents the minute(s).

that being said, the tiny hand is between 2 and 3-we can eliminate c and d.

look at the minute hand. it is on 9, which means 45

we can cross out 3:45 as the hour hand is not between 3 and 4.

this leaves us with 2:45

hope this helps :)
