A plane travels 600 miles in 3 hours. at this rate how far could the jet fly in 10 hours? math
IgorLugansk [536]
First you would have to find the distance it's going per hour.
600 \div 3
You will then get the answer of 200 m/hr. You can then plug in 200 m/hr to find how far the jet could fly in 10 hours
200 \times 10
You're final answer should be 2,000 miles
