4t+8=3(3.5t).

t= miles

Mark and Sandy wanted to have a race. Mark has an 8 mile head start and goes 4 miles per hour. Sandy decides to go 3 times as fast and goes 3.5 miles per hour.

**Steve**, Tuesday, November 12, 2013 at 8:23pmhow can 3 times as fast as 4mph be 3.5mph? I can't think of a good race scenario that reflects this equation.

Factor out a 4, and we have

4(t+2) = 3(3.5t)

Consider a small box of toys that weighs t pounds.

Medium boxes weigh 2 pounds more, and large boxes weigh 3.5 times as much.

How much does a small box weigh, if 4 medium boxes weigh as much as 3 heavy boxes?
