Question

The Grand Prix Formula 1 race this weekend is in Singapore. The race consists of 61 laps around a 5.067 km long track. At 225 miles per hour, how long will it take to go around once?

Answer 1

1 mile ≈ 1.6 km

5.067 km ≈ 5.067÷1.6 ≈ 3.2 miles

time travelled = distance ÷ speed
time travelled = 3.2÷225
time travelled = 0.0142 hour = 51.2 seconds
