Question

Sarah wants to find out how much time it would take to drive from her home to new york. at an average, she would drive at 55 miles per hour. if the distance to be covered is 1150 km and a mile equals 1.61 km, how much time will the trip take (to the nearest hour)?13 hours21 hours29 hours34 hours

Answer 1

since it's 55 miles per hour so you need to convert km to m so you are going to divide 1150 km by 1.61 km and you will get 714.3 miles then divide that by 55 miles and you will get 12.98 and to the nearest hour that is going to be 13 hours.

Answer 2

13 hours

Explanation:

Speed of Sarah = 55 miles per hour

Distance = 1150 km

1 mile = 1.61 km

So, 1 km =
`(1)/(1.61)`

1150 km =
`(1)/(1.61) * 1150`

1150 km =
`714.2857`

Now we are supposed to find , how much time will the trip take ?

`Time =(Distance)/(Speed)`

`Time =(714.2857)/(55)`

`Time =12.98`

Thus it will take 13 hours to complete the trip.

So, Option A is true.
