Question

How many kilometers could the red car travel in 12 hours? Write an equation to show your work.

a) 144 km; Distance = Speed × Time
b) 60 km; Distance = Speed × Time
c) 72 km; Distance = Time / Speed
d) 96 km; Distance = Time × Speed

Answer 1

To determine the distance a car can travel in 12 hours, we use the formula Distance = Speed × Time. Using an example where a car travels 150 km in 3.2 hours, we calculate an average speed of 47 km/h and then find it can travel 564 km in 12 hours using that average speed.

Step-by-step explanation:

To find out how many kilometers a red car can travel in 12 hours, we need to know the car's average speed. We can use the formula: Distance = Speed × Time. If we know the average speed of the car, we can substitute the values into the formula to find the distance traveled in a given time, in this case, 12 hours.

For example, let's say a car travels 150 kilometers in 3.2 hours. To find its average speed, we use the formula average speed = distance / time, which would be 150 km / 3.2 h = 46.875 km/h. Rounding to the nearest whole number, the car's average speed is 47 km/h.

Using this average speed, we can then calculate the distance it would travel in 12 hours by multiplying: Distance = 47 km/h × 12 h, which results in a travel distance of 564 kilometers.
