Some More Programs

Program 1: A car starting from rest travels as follows:
• During its first 2 minute of motion, it travels at a velocity of 10 km/min.
• The next 8 minutes it travels at a velocity of 25 km/min.
• The next 10 minutes it travels at a velocity of 40 km/min.
• After that it continues to travel at a constant velocity of 60 km/min.
Write a program which takes the time in minutes and print distance travelled by the car in Kilo meter.

t=int(input('Enter time in minutes: '))
if t<=2:
d=t*10
elif t<=10:
d=2*10+(t-2)*25
elif t<=20:
d=2*10+8*25+(t-10)*40
else:
d=2*10+8*25+10*40+(t-20)*60
print('time in minutes:',t)
print('distance travelled in km:',d)

Output

Enter time in minutes: 20
time in minutes: 20
distance travelled in km: 620
