Question

Joseph leaves work at 17:00. He drives 48 kilometres from work to home at an average speed of 64k(m)/(h). What time does Joseph arrive home?

Answer 1

He arrives home at 17:45

Explanation:

To calculate the time Joseph arrives home, we can use the formula:

Time = Distance / Speed

First, we need to convert Joseph's average speed from kilometers per hour to kilometers per minute.

Since there are 60 minutes in an hour, we can divide his speed by 60 to get the speed in kilometers per minute:

64 km/h ÷ 60 min = 1.07 km/min

Next, we divide the total distance Joseph drives by his average speed in kilometers per minute:

48 km ÷ 1.07 km/min ≈ 44.86 min

So, it takes Joseph approximately 44.86 minutes to drive home from work.

Finally, we add this time to Joseph's departure time of 17:00 to find his arrival time:

17:00 + 44.86 min = 17:45
