Answer:
time, t = 3.6 min
Given:
Distance covered, d = 49 Km
My travel speed, v = 89.3 km/h
Friend's travel speed, v' = 98.2 km/h
Solution:
From the formula of speed, distance and time:
[tex]time, T = \frac{distance, d}{speed}[/tex]
Time taken by me, T;
[tex]time, T = \frac{d}{v}[/tex]
[tex]time, T = \frac{49}{89.3} = 0.55 h[/tex]
Now,
Time taken by friend:
[tex]time, T' = \frac{d}{v'}[/tex]
[tex]time, T = \frac{49}{98.2} = 0.49 h[/tex]
Friend's wait time, t = T - T' = 0.55 - 0.49 = 0.06 h
In minutes;
t = [tex]0.06\times 60 = 3.6 min[/tex]
