A cyclist is moving at a constant speed of 10 m/s. How long does it take him to travel 43 km including a 5 minute stopped time.

As the cyclist is travelling with a constant speed, we can use the equation time = distance / speed

For ease of calculation we can convert the 43km into m. As there are 1000m in 1 km, 43km = 43000m

time = 43000m/10m/s = 4300s

To this we can add on the 5 minutes stoppage time (5 mins = 5x60= 300s)

So the total time is 4300s + 300s = 4600s

We could also give this in minutes (4600/60) = 76.67 mins or roughly 1 h 17mins
