The tourist

A man travelled a distance of 61 km in 9 hours. He travelled partly on foot at 4 km/h and partly by bicycle at 9 km/h.
Find the distance travelled on foot.

Final Answer:

s1 =  16 km

Step-by-step explanation:

s=61 km t=9 h v1=4 km/h v2=9 km/h  s = s1+s2 s = v1 t1+v2 (tt1)  s=v1 t1+v2 (tt1) 61=4 t1+9 (9t1)  5t1=20  t1=520=4  t1=4  s1=v1 t1=4 4=16 km
