Answer:
Exp35 km/h , 25 km/hlanation:
Let the speed of one cyclist is v and the speed of another cyclist is v - 10.
Distance traveled by the first cyclist in 2 hours = v x 2
Distance traveled by the second cyclist in 2 hours = (v - 10) x 2
They meet after 2 hours.
So the distance traveled by the first and the second cyclist is equal to 120 km.
2 v + 2 (v -10) = 120
2v + 2v - 20 = 120
4v = 140
v = 35 km/h
The speed of first cyclist is 35 km/h and the speed of another cyclist is 35 - 10 = 25 km/h.
Answer:
35 km/hr and 25 km/hr
Explanation:
Total distance is D.
Let speed of one cyclist be X km/hr.
Speed of second cyclist = ( X-10) km/hr
Now,
Distance = Speed * Time
Total distance D = Distance covered by slower cyclist + Distance covered by faster cyclist.
D = 2* X + 2(X-10)
120 = 2X + 2X -20
120 = 4X - 20
140 = 4X
X = 35 km/hr
Therefore, Speed of faster cyclist = 35 km/hr
Speed of slower cyclist = 35-10
= 25km/hr
