Leah was supposed to attend a party at 3:15 pm. She ran into car trouble that delayed her 35 minutes. Once she got her car fixed she also ran out of gas which delayed her 20 minutes. What time did Leah arrive at the party?

4:10 pm

Step-by-step explanation:

She was supposed to get there at 3:15, but she was delayed 35 minutes.

15+35 is 50. Since 50 is less than 60, we don't need to change the hour.

So 3:50, but delayed another 20 minutes.

50 + 20 = 70.

70 is above 60, so we add 1 to 3 which is 4. Then we subtract 60 from 70 which is 10.

Therefore it is 4:10
