Question 1121506: Vehicle A is traveling at 65 mph and travels a total distance of 1.6 miles. Vehicle B is setting at a standstill. Vehicle B waits until Vehilce A is a half mile away from it and decides to intercept Vehicle A. Vehicle B intercepts Vehicle A at the distance of 1.6 miles. So, how fast is Vehicle B traveling when it intercepts Vehicle A?

Vehicle A is traveling at 65 mph and travels a total distance of 1.6 miles.
Vehicle B is setting at a standstill.
Vehicle B waits until Vehicle A is a half mile away from it and decides to intercept Vehicle A.
Vehicle B intercepts Vehicle A at the distance of 1.6 miles.
So, how fast is Vehicle B traveling when it intercepts Vehicle A?
:
The way I see this, Vehicle A travels 1.1 mi while Vehicle B travels 1.6 mi
let b = the average speed of vehicle b for that distance
Write a time equation: Time = dist/speed
1.6%2Fb + 1.1%2F65
1.1b = 1.6*65
1.1b = 104
b = 104/1.1
b = 94.55 mph average speed
Vehicle B = Accelerating from from a standing stop
let v = accelerated speed of B
%28v-0%29%2F2 = 94.55
v = 198.1 mph
