Answer with Step-by-step explanation:
Cara plants 5 seeds in 2 minutes.
⇒ Cara plants 5×5 seeds in 2×5 minutes
⇒ In 10 minutes Cara plant 25 seeds.
Wade plants 3 times as many seeds in half the time as Cara.
⇒ Wade plants 3×5 seeds in 2/2 minutes
i.e. Wade plants 15 seeds in 1 minute.
In 1×10 minutes Wade plants 15×10 seeds
i.e. In 10 minutes Wade plants 150 seeds.
150+25=175
Hence, they can together plant 175 seeds in 10 minutes.
