Question

Mr.Smith has been on a train for 4 hours and traveled 320 miles.At this rate, how far will he have traveled in 5 hours?

Answer 1

400 miles would be traveled in 5 hours

Answer 2

To solve this problem we must find the distance travelled in an hour by the train
We can use the unitary method and find the answer
So that would be 320/4(km) is the distance travelled in an hour or 80km per hour
now to find the distance travelled in five hours we multiply 80*5(km)
so the train will travel 400km in 5 hours
hope it helped
