Answer:
1.2
Explanation:
To express the amount of time Oliver walks as a decimal, you can convert 3/10 hour to a decimal by dividing 3 by 10:
3 ÷ 10 = 0.3
So, Oliver walks for 0.3 hours.
Now, to find the total distance Oliver walks, you can use the formula:
Distance = Speed × Time
Distance = 4 miles per hour × 0.3 hours
Distance = 1.2 miles
Oliver walks a total distance of 1.2 miles.
