Answer:
10
Step-by-step explanation:
When the equation says that Jill bikes 2/3 hour at 18 mph, it means that the amount of miles she biked is 2/3 of 18. 18 divided by 3 is 6. 6 times 2 is 12, so she biked 12 miles. If she walks 2/5 hour at 5 mph, then she walked 2 miles because 5 divided by 5 is 1 and 1 times 2 is two. The question is asking how much more she biked than walked, so 12-2=10.
