Question

Alex drives at an average speed that is 1/6 of the average speed that Roy's train travels. Alex takes 20 minutes to travel 12 km in her car. Roy travels for 2 hours and 20 minutes on his train. How far does Roy travel to 2 dp?

Answer 1

Answer: 336.00 km distance of train

Explanation:

Alex = 20mins =12km We distribute to 1hr to find 60mins = 36km p/h.

Roy = 2hrs 20 mins and is 4x the speed of the car.

So 36km x 4 p/h = 144km p/h

2hrs and 20 = 144 x 2.3333 = 335.9952 = 336km
