Final answer:
To find out how many laps a race car can complete in 1.5 hours, given it can complete 8 laps in 1 hour, a simple multiplication by the proportionate increase in time gives the result: the car can complete 12 laps in 1.5 hours.
Step-by-step explanation:
If a race car can complete 8 laps in 1 hour, we can calculate the number of laps it can complete in 1.5 hours by setting up a proportion. In this case, we have the rates of laps per hour (8 laps/1 hour), and we need to determine the number of laps in 1.5 hours, which we will call 'L'.
Laps per Hour (LPH) = Laps (L) / Hours (H)
8 laps / 1 hour = L laps / 1.5 hour
We can solve for 'L' by cross-multiplying:
- (8 laps) × (1.5 hour) = (1 hour) × (L laps)
- L = 8 laps × 1.5
- L = 12 laps
Therefore, the race car can complete 12 laps in 1.5 hours.
