Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
At a roller derby, 4 teams are competing. Each team is made up of 10 members, and each member needs a pair of roller skates to compete in and another pair of skates as a backup. None of the skates have laces yet, so each member is offered 3 sets of laces per pair of skates. How many sets of laces have been handed out?

### Response:
 Kuna jumla ya timu 4 * wanachama 10 kwa timu = <<4*10=40>>40 wanachama wa timu.
Kila mtu anapokea jozi 1 ya sketi za roller za kushindana + jozi 1 ya sketi za roller kama akiba = <<1+1=2>>2 jozi za sketi za roller.
Jumla ya jozi za sketi za roller * seti 3 za kamba kwa jozi ya sketi za roller = <<2*3=6>>6 seti za kamba kwa kila mtu.
Kwa wanachama wa timu 40, jumla ya seti 6 za kamba kwa kila mtu * wanachama 40 wa timu = <<6*40=240>>240 seti za kamba zimegawiwa.
