Answer:

juliet collected 50 cans

Step-by-step explanation:

let x be rosanas cans

10+x+2x = 130

simplify

10 + 3x = 130

3x = 130 - 10 = 120

x = 120/3 = 40

rosanas cans = 40

juliets cans = 40 +10 = 50

santiagos cans = 50 x 2 = 100

but i think the question is wrong!!

Answer:

325 miles

Step-by-step explanation:

Given that,

A car travels 390 miles in 6 hours.

We need to find the distance travelled in 5 hours.

6 hours = 390 miles

1 hour = 65 miles

In 5 hours,

5 hours = (65×5) miles

= 325 miles

So, it will travel 325 miles in 5 hours.
