A car travels at an average of $50$ miles per hour for $2.5$ hours and then travels at a speed of $70$ miles per hour for $1.5$ hours. How far did the car travel in the entire $4$ hours?

Answer is B

Formula : Distance = Speed * Time

Dist travelled by car in 2.5 hrs = 50 * 2.5 = 125 miles

Dist travelled by car in 1.5 hrs = 70 * 1.5 = 105 miles

Total distance travelled = 125 + 105 = 230 miles
