yolanda drove 50 miles in 2 hours at a constant speed. use a proportion to find how long it would take her to drive 150 miles at the same speed.

Respuesta :

50/2=150/x
x=6

6 is the answer.
50 miles/2 hours= 25 mph 
150 miles/25 miles=the time it would take her to drive 150 miles going 25mph...

the answer is 6 hours :)
