Question

Convert miles per hour to meters per second. Round the answer to the nearest whole number. (1 mile = 1,609 meters, 1 hour = 3,600 seconds)


65 miles per hour = ???? meters per second.

Answer 1

Answer:

  29 m/s

Step-by-step explanation:

$65\dfrac{mi}{h}=65\dfrac{mi}{h}\cdot\dfrac{1609\, m}{1\, mi}\cdot\dfrac{1\, h}{3600\, s}=\dfrac{65\cdot 1609}{3600}\cdot\dfrac{mi\,h\,m}{mi\,h\,s}\approx 29\, m/s$

Answer 2

Answer:

29 meters per second

Step-by-step explanation:

Convert  65 miles per hour to meters per second. Round the answer to the nearest whole number. (1 mile = 1,609 meters, 1 hour = 3,600 seconds)

To convert, we will follow the steps below;

First lets change 65 miles to meters.

To do that, we will simply use proportion;

Let x represent 65 miles in meters

1 mile     = 1609 meters

65 miles=  x

cross-multiply

x = 65 × 1609

x = 104585 meters

65 miles = 104585 meters

when we see 'per hour'  it shows we are dividing by 1 hour

1 hour = 3600 seconds, this implies we will divide 104585  by 3600

65 miles per hour = $\frac{104585}{3600}$  =  29.05 ≈ 29 meters per second to the nearest whole number
