Answer 1

To match the speed of an object moving at 50 feet per second, the car must travel at about 34 mph after converting from feet per second to miles per hour.

Step-by-step explanation:

To find the car's required speed to keep pace with an object moving at 50 feet per second, you must convert this speed to miles per hour.

1. Convert feet per second to miles per hour using the conversion factor 5280 feet = 1 mile and 3600 seconds = 1 hour.
2. Multiply 50 feet per second by 1 mile/5280 feet to convert to miles per second.
3. Multiply the result by 3600 seconds per hour to convert to miles per hour.

Calculating the car's required speed gives us:

(50 ft/s) × (1 mile/5280 ft) × (3600 s/hr) = 34.09 mph (approximately).

The car needs to travel at about 34 mph to keep pace with the object.
