Given : Four friends had a competition to see how far could they hop on one foot. The table given shows the distance covered by each.
To find : (a) How farther did Soni hop than Nancy?
(b) What is the total distance covered by Seema and Megha?
(c) Who walked farther, Nancy or Megha?
Solution:
Name Distance covered (km)
Seema 1/25
Nancy 1/32
Megha 1/40
Soni 1/20
farther Soni hop than Nancy = 1/20 - 1/32
= 8/160 - 5/160
= (8 - 5)/160
= 3/160 km
= 18.75 m
total distance covered by Seema and Megha = 1/25 + 1/40
= 8/200 + 5/200
= 13/200 km
= 65 m
Who walked farther, Nancy or Megha
Nancy 1/32 = 5/160
Megha 1/40 = 4/160
5/160 > 4/160
=> 1/32 > 1/40
=> Nancy walked farther
