Answer:

The time required by both persons to complete the work T = 1.458 hours

Step-by-step explanation:

Given data

Time required by Joe to clear a lot T_1 = 2.5 hours

Time required by his partner to clear a lot T_2 = 2.5 hours

Time required by both persons to complete the work by working together

T = \frac{T_1 T_2}{T_1 + T_2}

T = \frac{(2.5)(3.5)}{2.5 + 3.5}

T = 1.458 hours

Therefore the time required by both persons to complete the work T = 1.458 hours

I need help with this, please. Your family is driving from Harrisburg Pennsylvania to San Antonio, Texas a trip of 1430 miles. Y
olga_2 [115]

Estimate the total amount you should plan to spend on gasoline for the entire trip

<em>Total distance of the trip</em> = 1430 miles

<em>After 350 miles, refill tank</em> = $35

This means 350 miles cost $35

1430 miles cost $x

solve using ratio

350 : 35 = 1430 : x

350/35 = 1430 / x

10 = 1430/x

<em>cross product</em>

10x = 1430

<em>Divide both sides by 10</em>

x = 1430 / 10

x = $143

Therefore, the total amount you should plan to spend on gasoline for the entire trip is $143
