Question

Olivia drives her car at 60 miles per hour for t hours. Ian drives his car at 50 miles per hour for (t+2) hhours. Write a simplified expression for the sum of the distance traveled by the two cars.

Answer 1

Olivia travels 60 miles/hr for t hours = 60t

Ian travels 50 miles/hr for (t+2)hrs = 50(t+2)

Sum of distance traveled

= 60t + 50(t+2)

= 60t + 50t + 100

= 110t + 100

Answer 2

d = 60*t + 50(t+2)

d = 60t + 50t + 100

d = 110t + 100
