Always use significant figure rules. remember that these rules apply to all numbers that are measurements. you travel 20.0 mph for 0.500 hour, 40.0 mph for 1.00 hour, 30.0 mph for 0.500 hour, and 50.0 mph for 2.00 hours. what is the total distance traveled? 200 miles 170 miles 165 miles 160 miles

Answer : d = 165 miles

Explanation :

We know that

If we travel 20.0 mph for 0.500 hour, then distance covered is 10 miles.

If we travel 40.0 mph for 1.00 hour, then distance covered is 40 miles.

If we travel 30.0 mph for 0.500 hour, distance covered is 15 miles.

If we travel 50.0 mph for 2.00 hours, then distance covered is 100 miles.

So, total distance covered will be 165 miles.
