From the given speed and time, the distance of the trip can

be determined.

Correct response;

Number of hours the trip will take when traveling 60 mph is $\underline{5\frac{1}{4} \ hours}$

<h3>How is the time taken at a given speed calculated?</h3>

Given;

Time required for the trip from Carville to Nikpath = $4\frac{1}{2}$ hours

Average speed for the trip = 70 mph

Required;

The duration of the trip when traveling 60 mph

Solution;

Distance = Velocity × Time

Distance of trip = $\mathbf{4\frac{1}{2}}$ hour × 70 miles/hour = 315 miles

Duration of trip when traveling 60 mph is therefore;

$Time = \dfrac{315 \, miles}{60 \ miles/hour} = 5.25 \ hours = \mathbf{ 5\frac{1}{4} \ hours}$

Duration of trip when traveling 60 mph = $\underline{5\frac{1}{2} \ hours}$
