A car moves with a speed of 20km/hrs for 5 minutes and then with speed

1.	A car moves with a speed of 20km/hrs for 5 minutes and then with speed of 60 km /hrs for the next 10 minutes the total distance covered by car
Answer» Answer: Speed (S1) = 40km/h Time (t1) = 15 mins = (15/60) hr Distance $d1 = (s1 Ã— t1) = 40 Ã— (15/60) = 10 km$ Speed (S2) = 60 km/h Time (t2) = 15 min = (15/60) hour Distance $(d2) = (s2 Ã— t2) = 60 Ã— (15/60) = 15 km$ TOTAL distance $(d) = (d1 + d2) = 10 km + 15 km = 25 km$

Answer:

Speed (S1) = 40km/h

Time (t1) = 15 mins = (15/60) hr

Distance $d1 = (s1 Ã— t1) = 40 Ã— (15/60) = 10 km$

Speed (S2) = 60 km/h

Time (t2) = 15 min = (15/60) hour

Distance $(d2) = (s2 Ã— t2) = 60 Ã— (15/60) = 15 km$

TOTAL distance $(d) = (d1 + d2) = 10 km + 15 km = 25 km$
