The winner of a 200 mile race drove his car to victory at a rate of 140.2159 mph. What was his time​ (to the nearest thousandth
Keith_Richards [23]

Answer: 1.43 h

Step-by-step explanation:

Velocity is V is defined as the change in position (displacement) d of an object in a specific time t:

V=\frac{d}{t}

Where:

V=140.2159 mi/h is the car's velocity

d=200 mi is the distance the winner car traveled

t is the time

Isolating t:

t=\frac{d}{V}

Solving with the given information:

t=\frac{200 mi}{140.2159 mi/h}

t=1.426 h \approx 1.43 h This is the winner's time
