Question

Can anyone help me thanks

Answer 1

Option B: 1.3 hours is the correct answer.

Explanation:

Given that:

Total distance = 140 miles

Speed on city roads = 35 miles per hour

Time travelled = 1.5 hours

Distance covered on city roads:

`Distance = Speed * Time\\Distance = 35 * 1.5\\Distance = 52.5 miles`

Distance travelled on highway = Total distance - Distance on city roads

Distance travelled on highway = 140 - 52.5 = 87.5 miles

Speed on highway = 65 miles per hour

Time =
`(Distance)/(Speed)`

`Time =(87.5)/(65)\\Time = 1.3\ hours`

Hence,

Option B: 1.3 hours is the correct answer.
