Susan and her family left their home at 1:15 P. M. and arrived at their destination 30 minutes later. At what time did they arrive?

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)

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
