Question

Stan's Subaru travels 280 miles on an average speed. If the car had gone 5 mph faster, the trip would have taken 1 hour less. Find the average speed. Help!

Answer 1

d = r*t

280 = r * t
280 = (r + 5) * (t-1)

Answer 2

that's it?

Answer 3

now you can solve by substitution

Answer 4

they both equal to 280

Answer 5

r * t = (r + 5) * (t-1)

Answer 6

so r*t=(180+5) (5-1)?

Answer 7

I ment (280+5)*(5-1)
