Question

4. The time taken by three runners to finish a 250 m race is 0.90 min, 1.05 min
and 1.1 min.
(a) Sharad won the race and Tarun came second, followed by Abhijeet.
Write the time taken by each of them to finish the race.
(b) What is the difference between the time taken by Sharad and Tarun to
finish the race?​

Answer 1

Step-by-step explanation:

d=250m

t1=0.90X60= 54 seconds

t2=63 seconds

t3=66 seconds

s1=250/54=4.629 m/s

s2=250/63=3.968 m/s

s3=250/66=3.787 m/s

difference between time taken by sharad and tarun to finish the race=63-54=9 seconds

therefore, tarun took 9 seconds extra to finish the race.
