50 POINTS!!!

Suzanne ran 3 3/4 miles in the morning and 4 1/2 ​ miles in the afternoon. How many kilometers did she run altogether? Assume 1 mile = 1.6 kilometers.

Answer 1

4 1/2 = 18/4
3 3/4 = 15/4

15/4 + 18/4 = 8 1/4 or 33/4

33/4 * 1.6/1 = 52.8/4 = 13.2

When assuming 1 mile equals 1.6 kilometers, Suzanne ran 13.2 kilometers in all.

Answer 2

Answer:- Total distance traveled by Suzanne in kilometers=13.2 kilometers.

Explanation:-

Distance traveled by Suzanne in the morning=
`3(3)/(4)\text{ miles}`

Distance traveled by Suzanne in the evening=
`4(1)/(2)\text{ miles}`

Total distance traveled by Suzanne=
`[3(3)/(4)+4(1)/(2)\text{ miles}`

`=(15)/(4)+(9)/(2)\text{ miles}`

`=(15+18)/(4)\text{ miles}`

`=(33)/(4)\text{ miles}`

`=8.25\text{ miles}`

Total distance traveled by Suzanne in kilometers=
`8.25*1.6\text{ kilometers}=13.2\text{ kilometers}`

Total distance traveled by Suzanne in kilometers
`=13.2\text{ kilometers}`
