Answer:

d = 780

Step-by-step explanation:

Remark

You can do this with a proportion which will save you figuring out the rate. I'll do it both ways

Proportion

480/8 = x / 13            Cross Multiply

8*x = 13*480

8x = 6240

x = 780 miles

======================

Remark

Often times we like questions to follow a formula. Here's the formula method.

Formula

d = r * t

Givens

t = 8 hours

d = 480miles

r = ?

480 = r * 8            

480 / 8 = r

r = 60

Second part

r = 60 miles per hour

t = 13 hours

d = ?

d = 60*13

d = 780 miles
