Jakes truck can tow a max weight of 5,000 pounds. What is the max number of horses he can take in his trailer at one time withou
Gre4nikov [31]

Answer:

He can take 5 Horses at max in his trailer at one time without going over the max weight his truck can tow. (Assuming the average weight of one horse to be equal to 1000 pounds)

Step-by-step explanation:

The no. of horses that can be carried by the truck can be found by simply dividing the maximum weight, that the truck can tow by the weight of a horse.

Max. No of Horses = (Max weight truck can tow)/(Average weight of one    horse)

The weight of a horse is not given in the question .Thus, we assume the average weight of one horse, to be equal to 1000 pounds, we get:

Max. No of Horses = 5000 pounds/ 1000 pounds

<u>Max. No of Horses = 5</u>
