Answer:
10*40
80*5
20*20
Step-by-step explanation:
20*20=400
80*5=400
10*40=400
To find the average speed she goes in one mile, simply divide 21 by 4, this gives you 5.25.
To get the answer for part B, divide 42 by 5.25, Wich gives you 8. You can always check your work by doing the opposite as you did to solve, so 8 x 5.25 should equal 42, which it does.
