5. Adam drives his car with an average velocity of 85 km/h eastward. How long will it take him to drive

NISA [10]

Answer:

x = 6.59 hrs = about 6 hours, 35 minutes

Step-by-step explanation:

Adam drives at 85 km / h. Let's set up equivalent fractions to see how long if he drives 560 km.

$\frac{85 km}{1 hr} = \frac{560 km}{x hr}$

Cross-multiply:

85x = 560

Solve for x:

560/85 = x

<u>x = 6.59 hrs = about 6 hours, 35 minutes</u>
