Question

In a race, Tinku runs 30 m.His teammate,Jessy,runs 5m less than Tinku.Tinku's other teammate,Erica,runs 2 m 20 cm more than him. what the total distance covered by Tinku and his friends in centimeters.​

Answer 1

Step-by-step explanation:

tinku runs=30 m

Jessy runs 5 m less

30 - 5=25

jessy runs= 25m

erica runs 2.20 m more then tinku=

30 + 2.20=32.2m

Tinku runs=30m

jessy runs=25m

erica runs=32.2 m

32.2+25+30=87.2

now convert 87.2meters to cm=

1m= 100 cm so 87.2 m = 8720.0

Answer 2

Step-by-step explanation:

1. Let the total distance run by Tinku and his friends be x.
2. x = (30 - 5) x 100 = 25 x 100
3. x = 2500cm
4. x = 2500 + (2.20 x 100)
5. x = 2500 + 220
6. x = 2720
7. x = 2720cm.

Tinku and his friends ran 2720cm together.
