Question

Maria traveled 265 total kilometers by train and car to visit her grandmother. She started her trip by traveling 80 kilometers by train. Then, she drove a car the rest of the way at 90 kilometers per hour. Which of the following equations can be used to solve for h, the time in hours that Maria traveled by car?

Answer 1

total kilometers = kilometers by train + kilometers by car

265 = 80 + kilometers by car

kilometers = rate * time  = 90* h

265 = 80 + 90*h
