Question

a car drives from toronto to whitehorse in 11 days and 27 minutes. the distance driven is 5455.7 km. what is the average speed?
0.39 m/s
5.73 m/s
5.30 m/s
175 m/s

Explanation:

Step1: Convert time to seconds

• Convert 11 days to hours: \(11\times24 = 264\) hours.
• Convert 264 hours to minutes: \(264\times60=15840\) minutes.
• Add the 27 minutes: \(15840 + 27=15867\) minutes.
• Convert minutes to seconds: \(15867\times60 = 952020\) seconds.

Step2: Convert distance to meters

• Given distance \(d = 5455.7\) km.
• Convert to meters: \(d=5455.7\times1000=5455700\) meters.

Step3: Calculate average speed

• Use the formula \(v=\frac{d}{t}\), where \(v\) is average speed, \(d\) is distance, and \(t\) is time.
• Substitute \(d = 5455700\) m and \(t = 952020\) s: \(v=\frac{5455700}{952020}\approx5.73\) m/s.

Answer:

5.73 m/s
