Bill ate 1/4 pound of trail mix on his first break during a hiking trip. On his second break, he ate 1/6 pound. How many pounds
tino4ka555 [31]
Since we know that he ate 1/4 pound one time, and 1/6 another time, we have to add up the fractions. 

1/4+1/6

LCM of 4 and 6 = 12

3/12 + 2/12 

Add the numerators: 

5/12

So, he ate 5/12 of a pound of bars in both breaks. 

Hope this helps!

In 2015, an autonomous vehicle drove from the Golden Gate Bridge to New York City at an average speed of 15.7 miles per hour. Th
ivolga24 [154]

The speed is the distance covered by an object at a particular time. The distance that is covered by the vehicle is 3,391 miles.

<h3>What is speed?</h3>

The speed is the distance covered by an object at a particular time. Therefore, it is the ratio of distance and time.

Speed = Distance / Time

Given that the journey took 9 days. Therefore, the time in hours will be equal to,

Time = 24 hours/day × Number of days

        = 24× 9

        = 216 hours

Also, given that the speed of the vehicle is 15.7 miles per hour, the number of hours for which it travels is 216 hours.

Distance = Speed × Time

              = 15.7 miles/hour × 216 hours

              = 3,391.2 miles

Hence, the distance that is covered by the vehicle is 3,391 miles.
