Starting at home, Ishaan traveled uphill to the gift store for 18 minutes at just 10 mph. He then traveled back home along the s

kvv77 [185]

The formula to find speed:

$speed = distance \div time$

We first need to find the distance to gift store:
18/60 × 10
=3miles

We can then find the time he used down hill:
3÷30×60
=0.1×60
=6 minutes

In total he walked:
3x2
=6miles

We can then find his average speed by dividing the distance by total time used:
=6÷(6+18)/60
=6÷24/60
=15mph

The answer is 15mph.

Hope it helps!

Combine the like terms in each expression to find the matching simplified expression.

34kurt

Answer:

See below.

Step-by-step explanation:

First one:

y + x - 2 - 6x = y - 2 + x - 6x = y - 2 - 5x

Second one:

5xy + 4x -5xy - 3x = 5xy - 5xy + 4x - 3x = x

Third one:

2x + 3 - x - 4 = 2x - x + 3 - 4 = x + -1 = x - 1

Thus:

Connect A to 2.

Connect B to 1.

Connect C to 3.
