Answer:
1 hour
Step-by-step explanation:
The time it takes to travel to a destination varies inversely as its speed
T= k/S
K= TS
Time= 2 hours
Speed= 40mph
K= 2×40
= 80
Therefore if the average speed changes to 80mph then the new travel time can be calculated as follows
T= 80/80
= 1 hour
Hence the new travel time is 1 hour
Answer:
0.1358 = 13.58% probability of a fatal collision with a pole or post
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
In this question:
1416 collisions with pole or post.
1416 + 2516 + 2585 + 896 + 947 + 231 + 1835 = 10426 total collisions.
a. What is the probability of a fatal collision with a pole or post?

0.1358 = 13.58% probability of a fatal collision with a pole or post
<span>Lo siento, no sé español, pero lo intenté.
Si se trata de "$ 16,000" para una docena de camisas que es 12, se dividiría "16,000 entre 12". Luego obtendrás 1,333.3 para multiplicar eso por 4 y luego obtendrás 5,333.3 a lo que responderás.
Esta es la ecuación,
16,000 / 12 = 1,333.3 x 4 = 5,333.3
Espero que esto ayude :-)</span>
