Naledi ya Halley e dikologa letsatsi dingwaga di le 75. Rraagwe Bill o bone Naledi e e rengwa Halley a na le dingwaga di le 30. Bill o bone Naledi ya Halley lekgetlo la bobedi a na le dingwaga tse di fetang tsa ga rraagwe go menagane gararo fa a ne a e bona.

Emily can peel 6 shrimp a minute and saute 30 shrimp in 10 minutes. How long will it take her to peel and cook 90 shrimp?
Bill o bone Naledi ya Halley lekgetlo la bobedi a na le dingwaga di le 30 * 3 = <<30*3=90>>90.
Naledi ya Halley e bonala morago ga dingwaga di le 75,  ka jalo Bill o bone Naledi ya Halley lekgetlo la ntlha a na le dingwaga di le 90 - 75 = <<90-75=15>>15.

First find how long it takes Emily to peel the shrimp: 90 shrimp / 6 shrimp/minute = <<90/6=15>>15 minutes
Then find how many batches of shrimp she needs to cook: 90 shrimp / 30 shrimp/batch = <<90/30=3>>3 batches
Then multiply the number of batches by the time per batch to find the total cook time: 3 batches * 10 minutes/batch = <<3*10=30>>30 minutes
Then add the peeling time to find the total time Emily spends: 30 minutes + 15 minutes = <<30+15=45>>45 minutes
