Joseph drives 125 miles in 2.5 hours. At the same rate, how far will he be able to travel in 6 hours?
aivan3 [116]

Answer:

In 6 hours Joseph will travel 300 miles.

Step-by-step explanation:

Firs we will find Joseph's average rate:

v = 125/2.5 (since 2 1/2 = 2.5 and average rate = distance/speed)

v = 50 mph

We need to find the distance d in t = 6 hr:

d = v*t

d = 50*6

d = 300 mi

In 6 hours Joseph will travel 300 miles.

HOPE THIS HELPS U OUT AND IF IT DID PLS MARK ME AS BRAINLIEST PLS :)

a lightbulb manufacturer would like to increase production from 1.4 million to 3.9 million lightbulbs per year. find the percent
Olegator [25]

Answer:

The percentage increase of the production expectation to 1 decimal place is 178.6%

Step-by-step explanation:

Here in this question, we are interested in finding the percentage increase in the production capacity of the hypothetical company;

We can make or have a formula for this to make our workings easier;

% increase = (new value - old value)/old value * 100%

From the question;

The old value is the former productive capacity which is 1.4 million

The new productive capacity is 3.9 million

Thus;

The percentage increase in the production capacity would be;

(3.9 million - 1.4 million)/1.4 million * 100%

= 2.5 million/1.4 million * 100% = 178.57%

But the question asks we should have our answer in one decimal place;

Thus; 178.57% becomes 178.6%
