Asked by an i oop

Dina and Masha start cycling on a 20 km bike path at the same time. When Dina reaches the end of the path, Masha still has 4 km of the path left to cycle. If Dina’s cycling speed is 10 km/h, how much time longer will Masha need to complete the path? PLZ HELP ME

D time = distance / rate = 20 km / 10 kph = 2 hr

M has covered ... 20 km - 4 km = 16 km
... in 2 hr ... 16 km / 2 hr = 8 kph

M has 4 km to go ... 4 km / 8 kph = 1/2 hr
