Answer:

The truck's speed is 68 6/7 miles per hour

Explanation:

Defining distance:

Distance can be defined as the product of rate and time:

Distance = rate * time

Since we're given the driver's distance (120.5 miles) and time (1 3/4 hours), we can determine the truck's speed (r) by dividing the distance by the time:

  • For the sake of the problem, we can use the decimal of 1 3/4, which is 1.75.

Distance / time = rate

120.5 miles / 1.75 hours = rate (miles per hour)

120.5 / 1.75 = r

68.85714286 = r

68 6/7 = r

Thus, the truck's speed is 68 6/7 miles per hour.
