Casi drove 135 miles in 3 hours. Use a proportion to find how long it would take her to drive 360 miles at the same speed.

galina1969 [7]

Answer:

8 hours

Step-by-step explanation:

We are given that

Casi traveled distance in 3 hours=135 miles

We have to find the time taken by Casi to drive 360 miles at the same speed using proportion .

Let time taken by Casi to drive 360 miles=x

We know that

Speed= $\frac{Distance}{time}$

Using proportion

$\frac{a}{b}=\frac{c}{d}$

$\frac{135}{3}=\frac{36}{x}$

$x=\frac{360\times 3}{135}$

$x=8$

Hence, the time taken by Casi to drive 360 miles=8 hours
