Answer:3 hours
Step-by-step explanation:
Juno jogs at rate of 6 miles and bikes at rate of 14 miles covering total of 48 miles.
Akima jogs at rate of 8 miles and bikes at rate of 12 miles covering total of 44 miles.
Let jogging be represented by j
Let biking be represented by b
For Juno, 6j + 14b = 48 ......... i
For Akima, 8j + 12b = 44.......... ii
Multiply equation I by 8
Multiply equation ii by 6
48j + 112b = 384 ........... iii
48j + 72b = 264 ............. iv
Subtract equation iv from iii
48j + 112b = 384
- 48j + 72b = 264
40b = 120
b = 120/40
b = 3
Number of hours spent biking is 3 hours.
