Jack usually mows his lawn in 6 hours. marilyn can mow the same yard in 4 hours. How much time would it take for them to mow the

Anuta_ua [19.1K]

Answer:

2.4 hours or 2 hours and 24 minutes

Step-by-step explanation:

Jack mows 1/6 of the lawn per hour while Marilyn mows 1/4 of the lawn together. Adding up those rates yields in their combined mowing rate:

$R = \frac{1}{6}+ \frac{1}{4}\\R=\frac{10}{24}$

The time required for them to mow the entire lawn is:

$t = \frac{1}{R}\\t = \frac{1*24}{10}\\ t=2.4\ hours$

It would take them both 2.4 hours to mow the lawn together.

a rental car agency charges 190 per a week plus .25 per mile to rent a car. How many miles can you travel in one week for 370

alekssr [168]

Let m represent the number of miles traveled. If the whole budget amount of 370 is spent, then ...

... 190 + 0.25m = 370

... 0.25m = 280

... m = 280/0.25 = 1120

For 370, you can travel 1120 miles.
