Tomas and Tasha were hiking at a speed of 3.5 mph. On their way back, they were tired and their speed was 2 mph. How long was the route if the way back took them 1 hour and 30 minutes longer?

Time: Approximately 2 hours and 21 minutes

Length: 6 miles

If this doesn't answer your question please read the explanation.

Step-by-step explanation:

1 hour and 30 minutes is 3/2 of an hour.

Therefore, we have them traveling at 2 mph for 3/2 hours.

distance = rate x time

2 mph * 3/2 = 3 miles.

3 * 2 = 6 miles.

time = distance/rate

Then there is 3.5 mph

3 miles/3.5 mph = 6/7 of an hour.

Adding them: 33/14 is reached (hours)

Approximately 2 hours and 21 minutes.

so a parallelogram is just like a square base times height. multiply 40 and 39 to get 1560 inches.

a triangle is base times height divided by two. so multiply 7.9 and 5 and then divide it by 2 to get 19.75inches.

the kite can be split into two separate triangles and added together to get the total area. 30 x 4 /2 which equals 60. make sure to double it for the two triangles making 120.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.
