steve traveled the first 2 hours of his journey at 40 mph and the last 3 hours of his journey at 60 mph . what is his average speed of travel for the entire journey ?
"answer average speed of travel = total distance travelled / total time taken total distance traveled by steve = distance covered in the first 2 hours + distance covered in the next 3 hours . distance covered in the first 2 hours = speed * time = 40 * 2 = 80 miles . distance covered in the next 3 hours = speed * time = 60 * 3 = 180 miles . therefore , total distance covered = 80 + 180 = 260 miles . total time taken = 2 + 3 = 5 hours . hence , average speed = total distance travelled / total time taken = 260 / 5 = 52 miles per hour . choice a"
add(divide(add(multiply(60, 3), multiply(40, 2)), add(3, 2)), subtract(divide(const_100, 3), const_0_33))
