Answer:
For 1 h = 10.5
2 h = 31.5
63.00 t = 6 h
Step-by-step explanation:
in order to find 1 h, you can divide 21 by 2 and get 10.5. To check whether it's correct you can keep adding 10.5 or multiplying 10.5 with the amount of h until you get the amount for each number. For example, 10.5+10.5=21 or 10.5×4=42.
I hope that helps!!
