Suzette ran and biked for a total of 34 mi in 3.5 h. Her average running speed was 6 mph and her average biking speed was 12.5 m
olga nikolaevna [1]

Answer:

From the information given

x is time for which she ran at speed of 6mi/h and

y is time for which she biked at speed of 12.5 mi/h

total time = 3.5 h

total distance = 34 mi

so

6x + 12.5y = 34 and

x + y = 3.5

x = 3.5 - y

6 ( 3.5 - y) + y = 34

6.5y = 13 which gives

y = 2 and this

x = 1.5

so suze ran for 1.5 h and biked for 2 h

CHECK

speed of run X time of run + speed of biking x time of biking must be = total distance covered

6 × 1.5 + 12.5 × 2 = 9 + 25= 34 mi

which is true

Irene places a mirror on the ground 24ft away from the base of an oak tree. She walks backward until she can see the top of the
soldier1979 [14.2K]
First, illustrate the problem:

24 feet is the distance between the tree and the mirror. 
4 feet is the distance from Irene's eyes to the mirror. 
5.5 feet is the distance of Irene's eyes from the ground.
4 feet is the distance of Irene from the mirror

From this, we can draw a right triangle and then use the Pythagorean theorem to solve for the height of the oak tree. Also, we have an option to use ratio and proportion between two similar triangles.
