The perimeter of a triangle = the sum of the sides

So.....we need to solve this

x + ( x + 3) + (x + 5) = 26

Can you take it from there, critical ??? [ P.S......if so....post your answer and I'll check it ]

Mmmm...this is a more interesting problem !!!

The radiator holds 480 oz of fluid and leaks at 4 oz / min

So...the number of minutes it takes to drain is just 480 / 4 = 120 minutes = 2 hrs

Since the truck travels at 35 mph...the distance it travels before the radiator is empty is

35 mph x 2 hours = 70 miles
