Answer:
Correct choice is B
Step-by-step explanation:
For the numbers -1 and 59, find the difference 59-(-1):
since 59-(-1)=60 and (two arithmetic means tells you there will be three intervals), two arithmetic means will be
- -1+20=19;
- 19+20=39.
The only correct sequence is -1, 19, 39, 59.
Let time be x distance be y
- 140x=y-(1)
- 290x=360-y-(2)
Put value in eq(2)
Put it in eq(1)
- d=1.2(140)=168m
