Chris rode his dog sled at a constant speed to alaska university and back home to his igloo. the trip was 60 miles each way and took him a total of 6 hours. he drove 15 miles per hour faster coming home than he did going to alaska university. find his speed for each part of the trip.

V=10mph when chris go home

V=25mph when chris  go to university

Step-by-step explanation:

Hello! To solve this problem we must take into account the following aspects!

1. the movement that is made in the sled is with constant speed which means that the equation that governs this movement is V=X/T , where X= distante, V=speed, t=time

First we calculate when Chris comes home

X=60MILES

T=6hours

Now we calculate when Chris goes to college considering that she travels 15mph faster

V=10mph+15mph=25mph
