Answer:

Option (D)

Explanation:

Oil (crude and petroleum) is one of the major resources on earth in which the economy of a country is largely dependent on. These are non-renewable resources, which take thousands to million years of years in order to form.

It is highly essential. Every day, a large quantity of oil is being consumed. According to the researches done in the year 2015, it has been observed that the average global consumption of oil was 95 million barrels each day.

It has a high demand, and so it is being regularly used, and it has also been predicted that the present global oil reserves would be highly exhausted within the next 50 years.

Thus, the correct answer is option (D).

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.
