So it took an hour an 15 minutes which means the distance traveled is their speed+1/4 of their speed, also any answers that have northbound going faster than 6km/h above south is not right so B and D seems to be out of the picture
How does 16+9=-7? Is it a typo?
Answer:
-16
Step-by-step explanation:
x/-2 = 8
cross multiply.
-2(-2) = 0 (because you're cross multiplying)
8(-2) = -16
x= -16
1,120 you multiply 8 x 70 = 560 + 560 = 1,120.
