Ian drives an electric car. He can drive 425 kilometres before he needs to stop and recharge his car. It takes 10 minutes to charge 50 kilometres. How long does Ian have to wait for his car to fully charge?

85 minutes

Step-by-step explanation:

425/50=8.5 10 minute increments

8.5*10= 85 minutes

85 minutes

Step-by-step explanation:

Of it takes 10 minutes to recharget 50 kilometres and we need to find for 425 kilometres, therefore

10 minutes = 50 kilometres

x minutes = 425 kilometres

Cross multiply

50 × x = 425 × 10

50x = 4250

Divide both sides by 50

x = 4250 ÷ 50

x = 85 minutes

good luck on your studies! : )
