Answer:
12.6 !
Step-by-step explanation:
x + y = 80
x being how many miles he bikes
y being how many miles he jogs
substitute y with 17 because 3.4 (miles) x 5 (days) is 17 miles for those 5 days
so now its x + 17 = 80
subtract 17 from 80 and 17 from itself
x = 63. now divide 63 by 5 (days) to get 12.6 :)
Answer:
Distance rode by Jamey per day in his bike = 12.6 miles
Step-by-step explanation:
Jamey rides his bike the same distance each day while training for a race. He also jogs 3.4 miles per day.
Distance ran by Jamey per day = 3.4 miles
During 5 days of training, he bikes and jogs a total of 80 miles.
Total distance covered in 5 days = 80 miles
Total distance covered in 5 days = Distance ran by Jamey in 5 days + Distance rode by Jamey in 5 days
Distance ran by Jamey in 5 days = 5 x 3.4 = 17 miles
80 = 17 + Distance rode by Jamey in 5 days
Distance rode by Jamey in 5 days = 80 - 17 = 63 miles
[tex]\texttt{Distance rode by Jamey per day }=\frac{63}{5}=12.6miles[/tex]
Distance rode by Jamey per day in his bike = 12.6 miles
