Answer:
2635.875pounds
Step-by-step explanation:
Converting all the units to pounds for unit consistency. Let's convert
1 1/4tons horse weight and 15ounce water bottle to pounds.
According to the conversion;
1 ton = 2000pounds
1 1/4 tons = (2000×5/4)pounds = 2500pounds
Similarly for the conversion of ounce to pounds;
1 ounce = 0.625pound
15 ounces of water bottle = (0.625×15)pounds
= 9.375pounds
The total weight of the horse, rider, and items in total will give;
2500pounds horse + 110pounds person + 9.375pounds water bottle + 16.5pounds basket
= 2635.875pounds
