Laura drove 638 miles in 11 hours at the same rate how long would it take her to drive 406 miles
shusha [124]

Answer:

Step-by-step explanation:

This is a d = rt problem; but since it is linear, then proportions will work too. Set up the proportion with miles on top and hours on the bottom:

\frac{miles}{hrs}:

Then put the numbers in where they go, keeping in mind that miles goes with miles and hours goes with hours in the ratios, and that our unknown is time (hours):

\frac{miles}{hrs}:\frac{638}{11}=\frac{406}{x} and cross multiply to solve:

638x = 4466 so

x = 7 hrs
