Question

An electric train is moving with a velocity of 120 km/h, how much distance will it move in 30 s?

Answer 1

Answer:

Explanation:

120km * 1,000 = 120,000 meters.

120,000 * 39.36 inches/meter = 4,723,200 inches.

4,723,200 inches divided by 12 inches = 393,600 feet.

393,600 divided by 5,280 lf/mile = 74.55 mph

74.55 mph divided by 60 minutes per hour = 1.24 miles/minute.

1.24 miles/minute * 30 minutes = 37.27 miles traveled in 30 minutes at 74.55 mph.

Answer: You are traveling at 74.55 mph which is 1.24 mpm times 30 minutes equals 37.27 miles in 30 minutes.
