at the race one car travels 190 mph while another travels 195 mph . how long will it take the faster can to gain two laps on the slower car if the speedway track is 5/2 miles long
assume xh
195t-190t=2x2.5
t=1h
one hour later,the faster can to gain two laps on the slower car
题目翻译:在一场比赛中,一辆车速度为190英里每小时而另一辆车每小时195英里每小时,如果赛道2.5英里,问那辆快车需要多长时间领先那辆慢车两圈?
设需要th
195t-190t=2x2.5
t=1h
1小时后,那辆跑得较快的车可以领先那辆跑得慢的车两圈赛道
assume xh
195t-190t=2x2.5
t=1h
one hour later,the faster can to gain two laps on the slower car
