Question 565973: PLEASE HELP ME SOLVE THIS WORD PROBLEM: A car goes 59 KM at the speed of 90 km/hr. For the rest of the distance the same car goes 50km/hr for 46 km. How many minutes did the car travel?

You know that t= d/r
First Part
d= 59 km , speed = 90 km/h
second part, d= 46 km, speed = 50 km/h
(46/50)+ (59/90)= 1.575 hours
1.575 * 60 = 94.5 minutes
