Question

Use the following equations to solve the problem. final distance = initial distance + (speed × time) . df = di + vt. 1.00 mi = 1.61 km. For an initial distance of 11.3 km, a speed of 35.0 miles per hour, and a time of 3.00 hours, what is the final distance in km? A) 49.3 km. B) 116 km. C) 76.5 km. D) 180 km.

Answer 1

is it 180?

>convert 35 miles to km
35/x = 1.00/1.61 (this is a proportion w/ miles on top and km below the bars)
35 miles = around 56.4 km
>plug it into the equation
11.3+(56.4*3)=180

*I'm not sure, I tried looking it up and someone said 116 b/c they didn't convert \-:
