A car is traveling at a speed of 65 mi/h. How long does it take to cover a distance of 235 m?
fgiga [73]

Answer:

It will take 8.09 seconds to cover 235 meters by car with speed of 65 mile/h.

Explanation:

Speed of the car = 65 mile/h = 65  1609.34 m/h = 104,607.1 m/h

1 mile = 1609.34 m

Distance covered by the car in t time = 235 m = mile

Speed-\frac{Distance}{Time}

104,607.1 m/h=\frac{\frac{235}{1609.34} mile}{t}

t=\frac{235 m}{104,607.1 m/h}

t = 0.002246 h

1 hour = 3600 seconds

0.002246 h = 0.002246 h × 3600 seconds = 8.09 seconds

It will take 8.09 seconds to cover 235 meters by car with speed of 65 mile/h.
