A red kangaroo jumps along at 40 km/h. At this rate how long would it take to jump 2 km?
LenKa [72]

 

The solution would be like this for this specific problem:

Given:  40 km/h

2 km

t = d / v
t = 2 km / 40 km/h
t = 0.05 h * 60 minutes = 3 minutes

 

<span>At this rate, it would take 3 minutes for the red kangaroo to jump 2 km.</span>

You own a motel and have a pricing structure that encourages rentals of rooms in groups.
zheka24 [161]

Answer:

$41

Step-by-step explanation:

  • One room rents for $68,
  • Two rooms for $65 each,
  • In general, the group rate per room is found by taking $3 off the base of $68 for each extra room.

So,

a_1=\$68\\ \\a_2=\$65\\ \\a_3=\$62\\ \\...

where a_n is the rate per nth room rented.

This is an arithmetic sequence, so

a_n=a_1+(n-1)\cdot d

In your case,

a_1=68\\ \\n=10\\ \\d=-3

Hence

a_{10}=68+(10-1)\cdot (-3)=68-9\cdot 3=68-27=41

This means if a group rents 10 rooms, the charge per room is $41.
