Final answer:
The formula for the trip is distance = speed x time, and the speed is found by dividing the distance by the time.
Step-by-step explanation:
To find the formula for the trip, we need to use the formula: distance = speed x time.
In this case, the distance is 1.2 miles and the time is 0.5 hours. Plugging these values into the formula, we get: 1.2 miles = speed x 0.5 hours.
To find the speed, we can rearrange the formula and solve for it. Dividing both sides of the equation by 0.5 hours, we get: speed = 1.2 miles / 0.5 hours.
Calculating this, we find that the speed is 2.4 miles per hour.
