Reggie made a bus trip of 162 miles He averaged 52 mph for the first part and 55mph for the second If the trip took 3 hours how long did he travel at each rate?

Answer 1

52 (T) + 55 (3 - T) = 162

Eliminate parentheses:

52 T + 165 - 55 T = 162

Subtract 165 from each side:

52 T - 55 T = -3

Combine like terms on the left side:

-3 T = -3

Divide each side by -3 :

T = 1

1 hour at 52 mph = 52 miles

2 hours at 55 mph = 110 miles

---------------------------------------

3 hours . . . . . . . . . . 162 miles bravo!
