Need to set up an equation for my honors alg. 3-4 class?

Question

i need help just setting up an equation for my homework with variables and for some reason i just cant come up with it.

here it is:

Tom and Tina set out on their bikes at noon and travel toward each other, meeting at 2:30 p.m. Tina's speed is 4 mi/h faster than Tom's speed, and their starting points are 50 mi. apart.

thank you in advance

Answer 1

2.5 hours = Time.

Your total is 50 miles.

x = Speed of Tom, x + 4 = Speed of Tina.

They both have to ride 2.5 hours each, so whatever the speed you have to multiply by 2.5.

The equation is 2.5x+2.5(x+4)=50
