Answer:To round 0.994 to the nearest tenth consider the hundredths’ value of 0.994, which is 9 and equal or more than 5. Therefore, the tenths value of 0.994 increases by 1 to 0.
0.994 rounded to the nearest tenth = 1.0

Answer:
Approximately 3771 times
Step-by-step explanation:
Let x be the number of times the wheels turn in 5 miles.
Given that, 1mile = 5,280ft
Thus, 5 miles=5 × 5,280ft=26400ft
From the question ,we can deduce the following ratios :
140 ft : 20 mins
26400ft : x
Cross multiply;
Divide through by 140.
For the answer to the question above, we'll have to use the formula for velocity which is v =<u> d
</u> t and d = vt
Since the total distance is given, therefore we can get the time and it will look like this.
220t + 250t = 1880
<u>470t</u> = <u>1880
</u>470 470
the problem indicates that the train runs 250kph
Let's substitute:
d = 250(4)
the distance traveled by Lian is 1000km
