Question
Dina and Masha started out on a 12 mi bike path at the same time. When Dina reached the end of the 12 mi, Masha still had 3 mi left to bike. If Dina’s biking speed is 8 mph, find Masha’s biking speed.

Dina took 12/8 = 3/2 hrs
So, if Masha's speed was x
3/2 x = 12-3
x = 6 mi/hr
So, if Masha's speed was x
3/2 x = 12-3
x = 6 mi/hr
;-;
x=6 mph
