Answer:  102.9 m

<u>Step-by-step explanation:</u>

First, use Pythagorean to find the length of AC

 AB²  +  AD²  = AC²

 50²  +   80²  = AC²

2500 + 6400 = AC²

             8900 = AC²

             94.34 = AC

Next, subtract 15 (the diameter of the circle) from AC to find the length of the straight line.

94.34 - 15 = 79.34

Next, find the circumference of the circle

C = πd

C = 15π

They are only walking around 1/2 of the circle so divide it by 2.

(1/2)C = (15/2)π

          ≈ 23.56

Add the straight line (79.34) and the half circumference (23.56) to find the total distance traveled.

79.34 + 23.56 = 102.9

Virty [35]

Answer:

7:12 a.m

Step-by-step explanation:

Given that:

Train to New York city leaves station every 7 minutes

Train to Boston leaves station every 6 minutes

Current time = 6:30 a.m

Time both will leave station together is obtained by finding the least common multiple of 6 and 7

Multiples of ;

6 = 6, 12, 18, 24, 30, 36, 42, 48, 54, 60,...

7 = 7, 14, 21, 28, 35, 42, 49, 56, 63, 70,...

The least common multiple of 6 and 7 is 42.

Hence, both trains will leave the station together after 42 minutes ;

Current time + 42 minutes

6:30 a.m+ 42 minutes = 7:12 a.m
