minutes

Answer 1

To calculate the time it would take each machine to travel 60 miles, use the formula Time (minutes) = Distance (miles) ÷ Speed (mph) × 60 minutes. Jeff Gordon's Car would take 40.2 minutes, Thrust SSC car would take 4.8 minutes, TGV Train would take 19.2 minutes, and Spirit of Australia Boat would take 11.4 minutes.

Step-by-step explanation:

To determine how long it would take each machine to travel 60 miles, we can use the formula:

Time (minutes) = Distance (miles) ÷ Speed (mph) × 60 minutes

Let's calculate the time for each machine:

A. Jeff Gordon's Car:
Speed (mph) = 60 miles ÷ 90 mph = 0.67 hr
Time (minutes) = 0.67 hr × 60 min/hr = 40.2 minutes

B. Thrust SSC car:
Speed (mph) = 60 miles ÷ 763 mph = 0.08 hr
Time (minutes) = 0.08 hr × 60 min/hr = 4.8 minutes

TGV Train:
Speed (mph) = 60 miles ÷ 186 mph = 0.32 hr
Time (minutes) = 0.32 hr × 60 min/hr = 19.2 minutes

Spirit of Australia Boat:
Speed (mph) = 60 miles ÷ 317 mph = 0.19 hr
Time (minutes) = 0.19 hr × 60 min/hr = 11.4 minutes
