Answer:
8 laps in 70 seconds is faster.
Step-by-step explanation:
If we divide 70/8 and 98/12 we get the following:
70/8= 8.75
98/12=8.16
8.75>8.16
The unit rate is 1 lap in 8.75 seconds and 1 lap in 8.16 seconds
Answer: The answer is D, obtuse angles must be larger than 90 degrees
Answer:

PS:
I could get my calculator to make the product as a fraction if you want.
I think it is about rates; Ian can pay his parents back in roughly 16 months. Ken can pay his parents back in 30 months.
Ian: 1000$ / 60$m = 16.6 m
Ken: 600$ / 20$m = 30m
