Answer:
Step-by-step explanation:
Given parameters:
Rate of walking by Lin = 13 miles in 5 hours
Rate of walking by Jada = 25 miles in 10 hours
Distance walked = 3.25 miles
Time of take off = 3:00
Solution:
The rate of their walking amounts to their speed;
Speed = [tex]\frac{distance}{time}[/tex]
Speed of Lin = [tex]\frac{13}{5}[/tex] = 2.6 miles/hr
Speed of Jada = [tex]\frac{25}{10}[/tex] = 2.5 miles/hr
To find the time; make it the subject of formula and solve for each person;
Time = [tex]\frac{distance}{speed}[/tex]
Time of Lin = [tex]\frac{3.25}{2.6}[/tex] = 1.25hr = 48 minutes
Time of Jada = [tex]\frac{3.25}{2.5}[/tex] = 1.3hr = 47 minutes
Time for each to arrive;
Lin = 3.00 + 1.25hr = 4:25
Jada = 3.00 + 1.30hr = 4:30
