Yup! If you do 2.9 x 1.2 it equals 3.48. If you're wondering how to get the decimal all you have to do is see the numbers behind the decimal. There is 2 numbers behind the decimal, therefore it means that the correct answer is 3.48 I hope this helps you!! :D
You would cross multiply. 14 over 31.5 and X over 10.5 10.5 times 14 is 147 divide that by 31.5 which is 4 1/3 and that is how fast she can run 4 1/3 mph
