The length of the base of an isosceles triangle is 5x - 6 The length of a leg is x. The perimeter of the triangle is 153. Find x.
Perimeter = sum of all the sides
153 = 5x-6 + 5x-6 + x
11x = 153+12 =165
x = 165/11 = 15
x=15

Speed=Distance/time
Here,
distance=15m
time=1sec
speed=15/1=15m/sec
Distance=Speed*time
time=15min=15*60sec=900sec
Distance travelled in 15 min=15*900=13,500m
=13500/1000 km=13.5Km
