Answer 1

Step-by-step explanation:

hey mate,

30 minutes = 30/60 = ½ hours

In ½ hours ball makes by machine = 500

In 1 hours balls makes by machine = 500 × 2/1

= 1000 balls

∴ In 3.1/2 (7/2) hours,

Balls make by machine = 500 × 2 × 7/2

= 3500 balls

hope this would help you!!

Answer 2

HELLO MY FRIEND THE QUESTION IS INCOMPLETE.I THINK IT SHOULD BE 3 1/2 HOURS AND BELOW IS YOUR SOLUTION-

3 1/2 HOURS

500:30=50:3

3 1/2 HRS=210 MINUTES

THEREFORE,

50:3=50x70:3x70

=3500:210

hence 3500 balls are made in 3 1/2 hours.
