Time = 1.4hours

Explanation:

Greetings !

Firstly, recall Speed-Time equation

`speed = distance / time`

given values:-

• speed = 65miles per hour
• distance = 90miles

required value:-

• time taken =?

solution/work-out

`speed = distance / time`

solve for the time by plugging in the given values to the equation

`time = (distance)/(speed)`

Thus,

`time = (90miles)/(65miles \: per \: hour)`

`time = 1.38hour`

which is approximately 1.4hour

Hope it helps!!!
