Answer:
a)17 min(i am not sure)
b) 80/100 = 56/x
cross multiply
5600 = 80x
x = 5600/80
x = 70
ans 70 miles
The second one is 70 for sure since 80% of 70 is 56.
The first one would just be 17r. You cannot get a number answer since time formula involves three variables and there is only 1 given variable.
