Distance/Rate/Time Word Problem -- Help!?

Question

Stressing over this word problem... been trying it for a good long time and...... basically I wish I were better at math. Help? :)

Red Riding Hood drives the 432 miles to Grandmother's house in 1 hour less than it takes the Wolf to drive the same route. Her average speed is 6 mph faster than he Wolf's average speed. How fast does she drive?

Answer 1

s = d / t

s +6 = 432 / (t-1)

s = 432/ t

432/t +6 = 432 / (t-1)

t for wolf is 9 hrs

s for wolf is 48 mph

s for Red Riding hood is 54
