Dina and Masha start out on a bike path 10 km long at the same time. When Dina reaches the end of the 10 km, Masha still has 2 km left to bike. If Dina’s biking speed is 5 km/h, find Masha’s biking speed.
Answered by Damon
dina takes 2 hours

masha went 8 km in that 2 hours
8/2 = 4 km/hour
Answered by HOLA
Masha's biking speed is 4 km/h because 10-2= 8 so she is 8/10 and that reduces to 4/5 which is 4 miles out of the 5 that dina's speed is.
