Divide the miles and time to find the speed.
14.4/3 = 4.8
28.8/6 = 4.8
43.2/9 = 4.8
57.6/12 = 4.8
All the answers are the same, so therefore the speed is 4.8 mph.
Okay so you are going to really just add 30 + 9 here and that means you have 30 tens and 9 ones or a 30 in the tens place and a 9 in the ones place.
I hope i broke that down well enough.
I hope this helped :)
H is equal to 8
M is equal to 15.3
20-12= 8
9+6.3= 15.3
Hope this helped
