The speed of the car was 2.6 m/s
Explanation:
The speed of the car is given by:
[tex]v=\frac{d}{t}[/tex]
where
d is the distance travelled by the car
t is the duration of the car ride
In this problem, we have:
D = 1500 yards is the distance between home and the school
d' = 650 yards is the distance covered by Carry on foot
So, the distance covered by Carry on the car is
d = D - d' = 1500 - 650 = 850 yards
Converting into metres,
[tex]d=850 y \cdot 0.9144 m/y = 777 m[/tex]
The total time of Carry's trip is
T = 20 min
And she spent
t' = 15 min
walking. Therefore, the time spent on the car is
t = T - t' = 20 - 15 = 5 min
Converting into seconds,
[tex]t = 5 min \cdot 60 s/min = 300 s[/tex]
Therefore, we can now find the speed of the car:
[tex]v=\frac{777 m}{300 s}=2.6 m/s[/tex]
