A. 720 miles
B. 12 miles
C. 8-6/7 miles
D. 12-7/7 miles
E. None of these

Answer 1

Please explain as well .

Answer 2

distance = rate(time) or d=rt
so
at 40 mph
d = 40(t+10/60) this is in hrs because of mph and we have time plus 10 minutes
for 30 mph
d= 30(t+16/60)
the distance is equal so we set them equal to each other like this:

40t + 400t/60 = 30t + 480/60 we multiplied thru

you should be able to get it from here.

Answer 3

if you cant ill help

Answer 4

Answer 5

ok
