Pozdechodim 11611

Mr. Pozdechodim missed the bus at 10.05. At 10.10, he passed Jindra. The bus travels at an average speed of 60 km/h and Jindra at 80 km/h. Will they catch the bus, which is 20 km from the next stop?

Correct answer:

s =  20 km

Step-by-step explanation:

v1=60 km/h v2=80 km/h Δ=5 min h=5:60  h=0.08333 h  s = v1 t s = v2 (tΔ)  v1 t=v2 (tΔ) 60 t=80 (t0.083333333333333)  20t=6.666667  t=206.66666667=0.33333333  t=310.333333  s=v1 t=60 0.3333=20 km
