What is the actual length of the​ truck?

1 inch equals 0.8 feet
The gridlines are spaced 1 inch apar

To calculate the actual length of the truck, we need to first determine the length of the truck on the gridlines.

Let's assume the length of the truck on the gridlines is given as 6 gridlines.

6 gridlines x 1 inch/gridline = 6 inches

Now, to convert inches to feet, we use the given conversion factor:

6 inches x 0.8 feet/inch = 4.8 feet

Therefore, the actual length of the truck is 4.8 feet.
