A car is driving down a road at a normal speed of 50 miles per hour. It enters a hilly area of gradual incline and decline, where it must drive 50 miles up hill and then 50 miles downhill. If this 100 mile section of road takes 2.6 hours to traverse instead of the expected 2 hours (the time it would take if the road was completely flat) determine the speed that the hills add or subtract when going over.
Answer:
Step-by-step explanation:
I'm going to assume that the car goes 50-x mph uphill and 50+x mph downhill.
x ≅ 24 miles per hour
26 mph uphill and 74 mph downhill

James bought 4 tubes of paint to use for an art project. He paid the same amount for each tube, and he spent less than $20 in all. Solve for the cost of tube of paint.
(You have to write it with inequalities, not an equal sign.)
Joseph must sell more than 20 ice cream cones in order to make a profit. He has already sold 6 cones. How many cones must Joseph still sell?
(You have to write it in inequalities, not an equal sign. For example, NOT 2=25, but like THIS: 2<25)
Answer: Problem 1: x<$5
Problem 2: 6 + c ≥ 20
Step-by-step explanation:
number of tubes=4
total=<$20
4(x)<$20
x<$20/4
x<$5
number of ice cream cones needed to make profit=20
number of ice cream cones sold so far= 6
how many left?= c
6 + c ≥ 20

Answer: In 1 hour , it will waste = 1.25ml
