المشاركة الأصلية كتبت بواسطة Dr.Sosa استاذ هنا كيف طريقة الحل 1. 1 mi is equivalent to 1609 m so 55 mi/h is: a) 15 m/s b) 25 m/s c) 66 m/s d)88 m/s

In this problem you need to convert the speed from mi/hr into m/s. To do so, we have to know the magnitude of each quantity in terms of the equivalent

Here we have

1 mi = 1609 m

and

1 hr = 3600 s

Therefore, to convert from bigger value into smaller one we need to multiply by the factor as follow:

55 mi/hr = 55*1609 m/3600 s = 25 m/s
