Explanation:
It is given that,
Focal length of the concave mirror, f = -13.5 cm
Image distance, v = -37.5 cm (in front of mirror)
Let u is the object distance. It can be calculated using the mirror's formula as :
u = -21.09 cm
The magnification of the mirror is given by :
m = -1.77
So, the magnification produced by the mirror is (-1.77). Hence, this is the required solution.

Force exerted by Justin=300 N
Here power= 600 W
distance traveled=10 m
time=5 s
power is given by P= Work done/ time
600=work/5
so work= 60x5=3000J
now work done= force* distance
3000=F *10
F= 3000/10
F=300 N
Let us first calculate the average speed of David,
Av speed = Distance traveled/ Time taken
We have, distance = 70 miles
Time = 
hours = 1.75 hours
Av speed = 
= 40 miles/hour
Another 120 miles will be traveled in time, t = 120/40 = 3 hours
