Answer:
The time at which they arrive is: 1:45 P.M
Step-by-step explanation:
Susan and her family left their home at : 1:15 P.M
They arrived at their destination at: 30 minutes
We need to find at what time did they arrive?
We will add 30 minutes into their starting time to get the time they arrive.
We know that:
1:15 P.M means, 1 hour and 15 minutes
Now, adding 30 minutes to this time we get the arrival time:
Arrival time = 1 hour 15 minutes + 30 minutes
Arrival time = 1 hour 45 minutes
Arrival time = 1:45 P.M
So, the time at which they arrive is: 1:45 P.M (1 hour and 45 minutes)
