Question

Jamey rides his bike the same distance each day while training for a race. He also jogs 3.4 miles per day.

Answer 1

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

 $\texttt{Distance rode by Jamey per day }=\frac{63}{5}=12.6miles$

Distance rode by Jamey per day in his bike = 12.6 miles

Answer 2

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 :)
