Please show work thanks!
Dina and Masha started out on a 10 km bike path at the same time. When Dina reached the end of the 10 km, Masha still had 2 km left to bike. If Dina’s biking speed was 5 km/h, find Masha’s biking speed.
Thanks again!

Let X be speed of Dina and Y be speed of Masha and let T for Dina
X*T=10
Y*T=10-2
X=5

T=2
Y*T=8
Y*2=8
Y=4
