Answer:

Time t = 3.02 hours

Step-by-step explanation:

Given;

Distance d = 350 km

Speed v = 72 mi/h

Since 1 mile ≈ 1.61 km

Converting the speed to km/h

Speed v = 72 mi/h × 1.61km /mi

Speed v = 115.92 km/h

Speed = distance/time

Time t = distance/speed = d/v

Substituting the values;

Time t = 350 km/115.92 km/h

Time t = 3.019 hours

Time t = 3.02 hours (to the nearest hundredth.)
