Question

A cable on a crane measures 89 yards 2 feet. How much total cable would be on 14 identical cranes? Convert the answer to larger units whenever possible. A. 1,246 yards 1 foot B. 1,274 yards C. 1,255 yards 1 foot D. 1,246 yards 28 feet

Answer 1

we know that  

1 yard=3 feet

Multiply (89 yards 2 feet) by 14

(89 yards 2 feet)*14=89*14 yards 2*14 feet-------> 1,246 yards 28 feet

convert 28 feet to yards

28 ft=(28/3) yards=9.33 yards

9.33 yards=9 yards+0.33 yards

0.33 yards=1 foot

so

9.33 yards=9 yards+1 foot

substitute

1,246 yards 28 feet=1,246 yards +9 yards+1 foot----->1,255  yards + 1 foot

therefore

the answer is the option

C. 1,255 yards 1 foot

Answer 2

This is a multiplication question. we have been given the value of one entity and we have to find the value of several similar entities.

Given is:

A cable on a crane measures = 89 yards 2 feet

So total measurement of cable to be used in 14 identical cranes will be 89 yards 2 feet * 14

we will multiply the yards by 14 and feet by 14.

so ,

89 * 14 yards = 1246 yards and 2 * 14 feet = 28 feet

Hence the answer is 1246 yards 28 feet which is option D.
