Answer:
To find out how long it will take a car to cover 870 miles at a speed of 35 miles per hour, we can use the formula:
time = distance ÷ speed
Plugging in the given values, we get:
time = 870 miles ÷ 35 miles per hour
Simplifying the right side by dividing 870 by 35, we get:
time = 24.86 hours
Rounding to the nearest hour, the answer is:
time = 25 hours
Therefore, it will take the car approximately 25 hours to cover a distance of 870 miles at a speed of 35 miles per hour.
