Respuesta :

7 miles:2.5 hours
10 miles:? hour

10×2.5÷7=25/7. As a result, It took him 25/7 hours or 3 4/7 hours to ride 10 miles. Hope it help!
The answer is 3.6. You have to find the unit rate for miles per hour. You divide 2.5 by 7 and you should get this long, ridiculous number. You don't have to use all that so round to the nearest hundredths to get .36. You multiply that by 10 to get the answer......3.6! :)
