Airlines schedule about 4.5 hours of flying time for the reverse direction. The distance between these airports is about 2,300 miles. They allow about 0.4 hour for takeoff and landing.
a. From this information, estimate (to the nearest 5 mph) the average wind speed the airlines assume in making their schedule.
b. What average airplane speed (to the nearest 5 mph) do the airlines assume in making their schedule? Jana divided a sheet of paper into 5 equal sections and colored 2 of the sections red. What percent of the paper did she color? A computer repair technician charges $50 per visit plus$30/h for house calls.
a) Write an algebraic expression that describes the service charge for one household visit.
b) Use your expression to find the total service charge for a 2.5-h repair job. Eric borrowed a total of $4000 from two student loans. One loan charged 5% simple interest and the other charged 4.5% simple interest, both payable after graduation. If the interest he owed after 3 years was$547.50, determine the amount of principal for each loan. Which expression can be used to check the quotient $$\displaystyle{646}÷{3}?$$
