Answer:
6 hours
Step-by-step explanation:
70 ÷ 4 = 17.5 ----- divide to find out how many miles she travels per hour.
Samantha is driving at 17.5 mph
105 ÷ 17.5 = 6 ----- divide to find out how long it will take to travel that distance.
distance ÷ time = speed
distance ÷ speed = time
1 km = 1000m
1 hr = 3600 s
189 km/h
189 * 1000 / 3600 m/s
189*5/18 m/s
945/18 m/s
315/6 m/s
105/2 m/s
52.5 m/s
in 10 s
52.5*10
525 m
so basically what you would have to do is set up your numbers. it would look something like this. 68
× 49
-------------
and would then multiply 9 by 8, 9 by 6. put it down below the line while making sure to carry the numbers if need be. then do the same with the 4 times 8, and 4 by 6.
