Fun Math Riddle!! To qualify for the big race, Enzo needs to average 60 miles per hour overall in his two warm?

To qualify for the big race, Enzo needs to average 60 miles per hour overall in his two warm-up heats, each heat one mile long. In his first heat he could only muster a 30 mile per hour average. How fast must Enzo drive in his second heat to qualify for the final? Will he be able to qualify?|||Heat one 2 minutes. To average 60 mph in 2 miles he has to do it in 2 minutes, so he can't do it.|||It is impossible for him to qualify!


In order to average 60MPH in both races of one mile in length, he total time must


be less than 2 minutes. By averaging 30MPH in race #1, he used up the entire


2 minutes of time. He cannot qualify.
